I need to take some time out for some vintage audio stuff.  I need to foam the OHM. Not trying to get Chas wired out, turns out it's in there no matter how you werrite it or say it.  The OHMs need to be foamed. 

Check out the small RV-6 ring in the middle, that is a standard size and the only size I know outside this one single set.  I'm hoping some one else has these Andre' size rings?

Big ones are over an inch wide, regular ones are even further less than an inch wide.  All dimensions and bolts are a lot bigger on this one and only set I've seen so far.  I have the scope, early production with label on mount and OTA.  Both labels with serial numbers but the numbers never were consistently maintained. 

 

Anybody else have these larger RV-6 rings???

I'm bringing this back up - again - since I'll be moving on to some RV6 soon.  I have aquired another RV6 with these jumbo rings, so I now have two sets.  One bit of info is that the second set came with an RV6 that has factory documentation about the OTA being a 6" Dynascope substitute for the Real Value (RV) version OTA. Are there any official "Dynascope" 6" owners that can verify the larger rings?  The hinge bolts have flat heads on the larger rings, dome heads on the regular size rings.

I picked up a RV6 not too long ago.I've got the narrower rings with the flathead screws.. What does that mean?
I've been trying to figure out the age Of my RV6. Mine has the moon pad feet, The narrower rings, Cast iron focus Assembly, finder scope with the Wider mounting screws, I have a red oval criterion tag riveted to the equatorial head. Any help on the age?

[DAVIDG]

 Your best indication of the age is to look at the date stamped on the clock drive motor. The date is usually on the edge of the motor.

There are two motors used, the Synchron and the Haydon.  The Synchron has a date. I don't know of any date data on the Haydon. 

The Synchron date is on the edge of the motor cover. It is the last thing in the line of print around the edge, month and year.  I think the Synchron were the first motors used followed by the Haydon. 

The red oval criterion tag riveted to the mount seems strange.

 

Pictures are about the only way to go on this one. My guess is it's a later edition if moon pad feet. Maybe one of the scrambles they did with whatever parts they could find during the final times. 

[CriterionRV6]

I looked all over the motor and there's no date whatsoever. It's weird because Somebody said earlier that the wider ring Have the
Flathead screws but I measured mine and they seem to be the narrow ones with the flathead screws.My equatorial mount has got a red oval Criterion name patch Riveted to it. Anybody have any ideas. Somebody said the moon pad were earlier models

[CriterionRV6]

New to this, Not sure how to add a photo

[apfever]

Moon pads came out around 1968 when Criterion brought out the RV-8. It was all part of the moon landing craze. The moon legs soon showed up on both 8" and 6"...erratically. The DEC housing also changed dramatically to a new casting for the RV-8 and that also started to show up on both 6" and 8" shortly after.  Criterion started going down after the moon landing craze was over like many of the makers did.  The RV-6 was often made with RV-8 parts and even Deluxe Dynascope OTA to get orders out. 

 

Did you see if the motor was a Synchron or a Hayden?

WOW, that is a nice looking RV-6!

Click the small picture above folks. It enlarges a lot.

 

The wording on the motor box looks engraved, that would be older. The motor is newer. The DEC housing is older (cast iron). The legs are newer. The small rings with flat head hinge bolts is a cross breed of hardware.

Everything considered, I'd say you have a later (newer) scope that might not be identifiable for age.  I'd go mainly by the legs and the Haydon motor.  Criterion distinctly put out some hodge podge scopes during their end times. They used any and everything they had to use up whatever was available for parts. This is the only explanation I have and I've had a few like this, and still have some of these cross over RV-6 with non consistant era parts.  CHECK your focuser housing. Criterion started with iron housings, then went to aluminum focuser housings. Use a magnet.

 

The RED tag Sure is PRETTY!  I wish I had one of those! That is first time I've seen that on a pier cap. I have no explanation for one.  Come on folks, let's see some info on that tag. It looks like yet another factory substitute. Maybe they found a box of them on a shelf but I've never seen that tag on anything before and I have some oldies.  Sure is Pretty!

 

The paint is not consistent. Some parts look normal flat black while others are wrinkle paint. Some one might have put this together from several at home.  Some of us here will do that, some of us here have several RV-6 projects at home.  I have 5 or 6 or somewhere around there.  Quinton and/or his dad have a handful also.  I know others have a few.  Can someone post a link to that string with all the RV links in it?  It seems this one scope has more strings in this forum than any other given scope.  I commend 'CriterionRV6' for consolidating by using an old string.

I wonder if the number "6436" on the motor is a date code -- 1964, 36th month... ?

[CriterionRV6]

I did post that earlier and I did check the focus housing. It is made of iron.It's magnetic not aluminum. I restored this.The previous owner had spray painted everything black. I repaired and painted the tube, Repented and touched up all the black, Repainted the The peer with the hammered paint. The Mirrors looked Okay , but I might redo them sometime In the future. I owned one in the mid seventy And wanted this to look like it.

I think this was spiced up. Nevertheless that project succeeded! What a beauty.

I just snagged an RV6 today. I need it like a hole in the head but I couldn't resist. It's a nostalgic

thing. I'm looking forward to a little resto work. The mirror is in perfect shape.

[CriterionRV6]

Looks like an older one say early 70s
Check the drive motor See if it'sgot a date on it. Hope the hole in your head gets better..lol

Am I just looking at reflected sky, or are those tube rings blue?  If they are blue, can you tell me where you bought it?  I painted my tube rings blue about a year before I sold my RV-6 in 1975.

I thought they were slightly darker blue, though.  And my mount didn't have a lever on the side, just a big bolt with a socket head (I think).  Of course that could be a later addition.

(Addendum: I'm not sure if I painted mine blue or just seriously considered it.  The color would have been Ford engine enamel, which is what was available to me at the time.)

Didn’t they inscribe the date and other data on the mirror? 

[CriterionRV6]

The scope that I acquired has nothing on it other than "50" Scratched into the glass.
I assume that's the focal length.

[Gil V]

The date on the Synchron motors are stamped on the curved sides, not on top. Hadron motors might be the same?
