Thanks for everyone’s insight, here is a pic of the badge.  Makers mark is <BOL>.  It’s a beautiful little scope, I’d love to complete it.

Jim

it is very nice.  i like the colour scheme.

 

bol in a diamond is an exporter's mark.  it stands for "bushnell optical laboratories" and is also commonly found on bushnell binoculars, many of which also had marks identifying the actual japanese maker.  

 

bushnell was one of the first western import companies to form their own export company in japan.  it yielded some tax benefits.

I just bought a Sky Chief Jr back in April.  It arrived "In the wooden box and fully operational."  I can take measurements of threads, overall lengths of items, take pictures.  If you have a way to duplicate items, I could most likely send them to you (as long as they are returned).  A few items that stick out- There are grub screws that need to be removed if you fully disassemble the altitude adjustment for a cleaning.  I had bore wear and had to shim the shaft- this was necessary to eliminate the "backlash" when adjusting the altitude.  My lens cell was not parallel to the tube.  After cleaning the lens, I had to shim the lenses in the cell to get it performing correctly.

the Lemmon714 scope (G series SN) has the finder on the focuser

the Red Giant scope (I series SN) has the finder on the tube.

 

just an observation.

I'm looking around for some rings to use with my lovingly restored Edmund Super Space Conqueror. 

 

20220728_214253.jpg

 

As you can see, I'm using stacks of cork between the tube and the much-oversized Mizar rings currently adapted to the original saddle with aluminum stock. That cork isn't going to last very many observing sessions in this dew, and I feel it like I owe this setup a solution that will look nice and not scratch the paint job :) Please let me know what you think.

Those parts are fairly unobtainium because they are cast from crappy metal that degrades with time and they break often.

Az and alt blocks are not the same

Mine broke over the years. The mount became unusable. I’ve since repurposed the tripod (legs and hub). My Mayflower has another ride.

This is an RV6 worm block that I grabbed a few days ago and placed on the mount. No big endeaver, it was loose on the table. It engages but not perfect. These worm blocks have plenty of meat to slope and tilt the worm for a best fit that would work. I haven't checked for worms in the heap pile mostly the wrinkle black type stuff. I might as well start with the stopper feet and clean it up from the bottom. I'll deal with the missing worm block on mine when I get there. Probably leave it blank since I can do the azimuth by hand with modest preload. Maybe some milk jug.

I messaged the seller twice on Facebook and never received a reply.

Good luck

Does anyone know if there is an official name to this style of ring handle bar that's on a number of vintage refractors? Or if there is a company that manufactures them currently? I would like to get one for one of my modern refractors.

I'm going to have a longer chat with the owner about that one. It's apparently a wheel from a Singer sewing machine :)

I think that’s a picture of the Great Wetherell Refractor. Tim Wetherell fabricated that scope. It.s a one-off and a beauty. Tim sold it to CN member Derek Wong and it moved from Australia to Southern California. Here’s a thread about it:

There was also an article about it in Sly and Tel about ten years ago.

These are the caps I've been printing for myself.  I don't have any white material.  This is silver PLA with shiny bits in it.  They go on and off pretty easily but stay in place well.  They are flat on the outside and inside.  PLA is pretty stiff; probably PETG would be a better choice, as it's a bit more flexible and also more UV and temperature resistant.  Buy me a roll of white PETG and I'll make you as many as you want.  https://www.amazon.com/dp/B014VM9724

I am looking for a Meade LX200 Classic computer main board (the one inside the bottom cover) with 3.34 ROM chips.

 

Please let me know what you have.

I'm looking for a Cave or Cave/Starliner-style shaft counterweight, 5-10 lb, 1.5" bore or smaller. I can bore out 1" ones but bore > 1.5" is not going to be useful.  I'm not looking for the full size big one; don't need that much weight.  It doesn't have to be in great cosmetic condition and it's OK if the setscrew is missing or messed up.

 

DM me if you've got such an animal.  Bonus points if in SoCal where I could pick it up.  If I can't find one I'll just fabricate, but I figured I'd ask.

I assume your taliking about a allen head (hexhead) bolt. The last time I tried to buy one in a smaller size it was smooth without a knurled edge. The change in style seems to have happened fairly recently (between restoring my Mizar  and Polaris mounts). I need to check an incrediblitly stocked hardware store fairly near me to see if they still have old stock.

I just bought a used Astroscan here in Arizona. I would love to find a strap for it. A base would be great as well, right now I'm using a dog bowl.  It came with the scope!  DONT LAUGH~! grin.gif  As a side note, I did find the S.N. on the registry listed on the site. 41931.  Its Made in USA and has a black tube for your records.smile.gif

I also had an AstroScan that was missing the strap.  I went to Goodwill and Salvation Army stores, found a cheap bag with a suitable strap, bought it, removed the strap, and placed the bag back in the donation can.
