I will say between a 7, a 7TE, and a 7TE-2 there are slight differences, but basically the same.  It could be a little different label, a slight modification of the mount, or the tripod legs.  The wood boxes could have different layouts.

 

I have a 7TE-2, and it looks like the one  in the instructions.

 

 

The 500kb relates only to a single post, not the entire thread.  If you end up with 10 posts in a thread, each of those 10 posts can each have a total of 500kb.

I will send a pic of the inside of the case once I get all the styrofoam peanut debris out of it ! It does have the metal ep tray !

Huh... I was hoping there would be an obvious model number on it. This page may have some useful information. Oh... and do tell us if that is a Royal Astro mark next to the serial number...

Based on the serial# I'm going to take a wild guess and say 1964.

It also has the rounded hub with no level ! All the glass ie. front lens, eps, finder etc. looks excellent, just dusty ! The finder has the adjustable, metal lens cap for the front, could not see the smaller rear cap, yet ! So far I am quite happy !

Also I note that the front lens cell has 3 sets of adjustment screws ! The lens is perfect save for dust !

Is mild soap such as Dawn what to use to clean the tube and other metal components of dirt / dust ? What is the best for very small areas of mild corrosion on the underside of the metal hub etc ?

The number on my 7TE-2 is 261295.  It's hub isn't rounded and has a bubble and the azimuth circle.  The lower part of the wood tripod legs are square.  It still has some stubborn green felt on it's tube from the box it was in.  The lens cell is adjustable.

The 046xxx - 046xxxx are from '59-'60.  Yours is one of the higher numbers I've seen, so I would guess early '60.

You mean early 60’s not early 1960 in singular terms ?

As a point of interest, the lady I bought this scope from had intended to give it to her 10 yr.old grandson to learn astronomy ! At some point she determined that he was too young, before he got his hands on it ! Thank God, lol !

1960, singular term.  We really need Stephen to stop by this thread.

Dawn should work, but lately I've been using (thanks to Terra's suggestion), Awesome which is only a $1 at Dollar Tree. As far as mild corrosion, if it's on painted parts, there's not much you can do this side of a repaint, but sometimes you'll be surprised how good some parts will look after cleaning/wiping them with a light oil like WD-40.

The lite corrosion is up under some of the mount assembly like the hub, I think I will use WD40 and a cloth ! There are a couple of black paint areas that have small chips / wear marks so I will probably use something like shiny, black Tremclad to touch them up ! Or should I leave them alone ? I will check out the Awesome first ! If you read about Mr. Clean Erase it is recommended for all kinds of delicate / heavy cleaning so maybe it is another good alternative but not on glass lenses !

Mr. Clean erasers are slightly abrasive so maybe a little dulling on shiny paint. For cleaning OTA tubes you might try Turtle Wax polishing compound (the mild white stuff), followed by car wax. I've done it several times with good results.

I think you will find Mr Clean Erase isn’t very abrasive, you can use it on glass top stoves, other types of glass, painted walls, woodwork etc. ! You would only be rubbing the scope surfaces lightly for a very short while !

Hello LDW47, nice find indeed!!  A few questions later on.

 

Here is the dating information on your scope. I've posted this in the past, but wanted to discuss again here to help clarify what's been talked about with respect to the time frame of your scope in the Tasco lineup.

 

Also thks for helping out DreamWeaver!

 

The lowest range of Tasco "304 Power" 046XXX scopes go back to before May 1959 based on a sales receipt. And the first version of the "304 Power" instruction sheets are sans the border outline.

 

LDW47, your serial number 0461123 is newer than the first group of 6 digit 046XXX Tasco "304 Power" versions. This is what I call the second version of the "304 Power" model.

 

Note that the description of 7T or 7TE is never mentioned in either version of the "304 Power" instructions with or without the border. You have the second version of the instruction sheet with the border. Most likely Tasco was calling the scope a 7TE model by late 1959 based on sales literature if not earlier.

 

Based on my documentation, many of the 7 digit serial numbers beginning with 0461052 thru 0462257 have been found with the border on the "304 Power" manuals. The highest 7 digit serial number I've seen is 0462349.

 

Also for reference, serial number 0461193 had the border on the "304 Power" manual and was packed with November 1959 newspapers FWIW.

 

So your scope I believe would date from the latter half of 1959.

 

The 060XXX serial number scope start possibly as early as mid 1960.

So I will reference it as an early Model 7TE ?

At this point I really appreciate the expert help I have gotten on this scope ! An insight into the history / workings of these older scopes, to me, is important as they won’t come around again ! And also being that I am a bit of a perfectionist, lol ! I am hoping, in the future, that I can gain even more info on these wonderful scopes from the experts that be, even on small, trivial details ! A pic(s) of the inside of the wooden case with mount components, eps etc. will be forthcoming in a bit !

So I will reference it as an early Model 7TE ?

Only because there are so many variations of the 60mm x 910mm models called per their instruction booklets listed below, that I consider your scope to be the "Tasco 304 Power" version.

 

Of course it is just my personal opinion, but for me it is the only way to try and keep all the different variations of the Tasco 60mm x 910mm straight. grin.gif

 

Here are the different versions based on the instruction booklets found with the scopes I've documented and or own:

 

"Tasco 152 Power"/"Tasco 227 Power/"Tasco 228 Power"/"Tasco 304 Power" and then finally (7T/7TE/7TE-5) named "Tasco 7TE 304 Power"/"Tasco 7TE-2 304 Power"/"Tasco 7T 300 Power" and last the "Tasco 7TE-5 500 Power" version.

 

I like to first use what the instruction sheet or manual calls the telescope. If the manual is missing or does not match the version in the box for various reasons (scope crated during model changeover and or revised manual not available yet or even the previous manual was thrown in the box by mistake etc.), then I use sales literature for that model if it exists. Also around mid 1960, the wooden boxes came with an assembly diagram calling the scope a 7TE inside the upper lid.

 

I also use the serial number to help confirm to identify the exact model as well. Generally speaking the groups of serial numbers with the same prefix match an exact model version. But as expected there are some exceptions with the lowest and highest serial numbers of a group which appear to be based on model change over in most cases...but not all. frown.gif

 

Also Tasco started using REG NO's on the name tags and or wooden boxes to help identify the exact model as well. Revisions were made on some models every year or two, so a real mess for the warranty dept at Tasco to assist when sending a scope back in for repair and or to just sending replacement parts.

A quick look inside the case, I spread the components out so they can be seen, everything but the tube, legs and manual ! Waiting on a 40mm ep, some rings and a hybrid diagonal ! Then I will assemble it for a quick try and then a bit of restoration !

Do you see any evidence of gold/silver foil rectangular Passed sticker on the bottom side of the focuser housing? See ref pic.
