I picked up a very old Mogey mount.  early 1900's late 1800's.  It came with a 3.5" refractor.  Not so sure the OTA is Mogey.  The OTA has a wood tube.  Very nicely made.  There are no markings on the OTA.   Anyone know which manufacturer used wood tubes?  Rumors are Clark did.  However, I doubt the OTA is Clark.

Basically all the old ones did, I think. Fraunhofer, Merz, Steinheil, Zeiss (ULTRA rare!), Clark, etc. 

 

Could we get some pictures, please?

 

 

Clear skies!

I will strip off the paint and see what lurks underneath.

 

I have already noticed that the OTA near the lens  (about 6" Back) had a hole through which a bolt went because on the inside of the wood tube I can see the impression of where a square nut used to be.  This seems classic of a lot of very old refractors to use a rod near the lens to raise the OTA up and down.  I think someone bought the Mogey mount later and put this OTA on it.

Does not look like Clark focuser or finder, finder picture attached. If you want I can take a picture of two focusers.20170813_154924 s.jpg

Does anyone recognize the finder.   I have not seen any finder like this.  The cross hairs are missing but it looks like there are 3 of them instead of two.  Have never seen cross hairs like that before.

going to strip the paint off.  Everything is painted that color. The tube, the mount and the tripod legs.

The finder and it's objective end mount is very distinctive, the way it is clamped on what

appears to be the finder's dew shield.

I think that feature should help identify the telescope.

Have a look thru the Cyclopaedia of Telescope Makers:

https://ui.adsabs.ha...c, bibcode desc

My first thought while viewing your photos is France because the brass turnings

reminds me of the old brass French field glasses.

Thanks Robert, but not one match.  Sure was great searching through all that data.

Mogey certainly made a 3.5" refractor. In the ad I did notice that the finder looked strangely large at the objective for an old scope. Perhaps when you remove the paint you'll find the makers name on the back of the focuser, the cell, or on the knob. That said, I believe there's still a good chance the OTA is a Mogey. Whatever it turns out to be, I still think it was a wise purchase.

It would be nice to see the mount.  I will hazard the guess that this is an early Mogey, right after they took over William Gregg's optical business in the1880s.  Very nice find.

I rather doubt this will be helpful, but FYI there are some (low quality) scans from a 1927 William Mogey catalog on-line here:

 

http://cgi.ebay.com/...em=143931696886

 

Most relevant may be the 6th picture (pp. 18 - 19 of the catalog), that shows the "Class B" and "Class C" mounts were indeed sold separately.

 

Since eBay ended-auction pages are eventually erased, here's a downloaded copy of the photo, jpeg-compression artifacts and all ......

Edit:  P.S.  The same text and illustrations appear on pages 20-21 of the 1932 catalog, for which much clearer pictures were posted in a separate eBay auction ( https://www.ebay.com/itm/303895923292 ):

From pp. 2-3 of the William Mogey & Sons 1932 catalog, shared here mainly because of the company history summarized on the top of page 2 at left:

 

gallery_363526_16547_611135.jpg

 

Edit:   There is additional discussion and photos of the 1932 catalog in the CN forums here:  https://www.cloudyni...iam-mogey-sons/   including a defunct link to a PDF scan of the entire catalog.   CN member Wisconsin Steve who started the thread and provided that link may have a copy of the PDF and/or a currently valid link ?

 

P.S.   According to the this entry, the Archives at Rutgers University contain a copy of the 1917 catalog:   https://archives.lib...l_objects/31331

The early Clarks utilized wooden tubes. We have a 5” at the Cincinnati Observatory.

Thomas, Denmark

To the list of telescope manufacturers who used wooden tubes early on, you can add Henry Fitz ... here are two photos of a Fitz 6-inch rich field short focal length refractor (comet seeker) with a mahogany tube:

 

gallery_363526_16547_384344.jpg

 

(the complete PDF biography of noted comet-hunter / amateur-astronomer Leslie Peltier from which the above screen-capture was taken can be found archived on the AAVSO's web site here:  https://www.aavso.or...s-eBook_(2).pdf  ... I highly recommend downloading the PDF, not only for the interesting biography but also because it allows you to zoom-in for closer examination of the photos).

 

Speaking of early wooden tube refractors, from the PDF just cited I learned that the oldest operating telescope in the United States is at Cincinnati Observatory in Ohio, and is open to the public !   The wooden (mahogany) tube 11-inch refractor's objective lens was made in or prior to 1842 in Munich, Bavaria (later to become part of a unified Germany):   https://www.youtube....-fAJsrXrc&t=33s
 

Enjoy, and good luck ....

Well, cleaned the paint off the focuser and nothing providing a hint of who made the scope. 

 

I think the finder is something that got added later.  It is mostly aluminum.

It is going to take a lot of aircraft remover to clean the paint off the tube, mount and tripod legs

I must admit that a wooden tube is nice and light.

is there a list of what companies used wooden tubes.  Also, why wooden tubes when so many scope were made from brass and steel.

I have the type B mount without the setting circles. Someone changed out all the locking knobs with round knobs instead of lever controls.  I will take a picture.   The mount is very heavy.  I was surprised when I lifted it.   My Unitron 152 mounts are lighter most likely because they are aluminum while the Mogey is steel and brass.

The mount has WD mogey Bayonne NJ. on it.    Mogey was at that location from 1892 to 1911.
