I don't know if they've sold but someone's been advertising the mechanical drive recently on the regular sites.

So far everything is cleaning up well. I'm not planning on repainting any part of the scope except maybe refinishing the tripod legs. I like to have the original finish as long as its not too rough. 

Toady I'll start on the EQ head and hopefully have it set up for pics and viewing soon.

The objective cleaned up well. Also, the finder-scope eyepiece was very dirty but after a disassembly and cleaning it turned out very nice. I like the fine double cross hairs too. 

Looks like you’ve got yourself a real keeper there Rolando! I love the idea of putting it on wheels and leaving it set up in your garage. Then you could get a lot of use out of it!

Great find! Could not have happened to a better or more capable person! That scope - and the folks here - lucked out!

Every time I’m away from the forum for a day or two, I come back and discover Rolo has scored another amazing classic scope!  Congratulations Rolo!  Looking forward to seeing it all cleaned up and put together, and first light report.

I think he has been asking $3K for a weight drive.

That lens is in good shape.  When i got that mint M152 the lens had to be sent to Unitron for a cleaning as it had fogged up  That scope sat in the case from around 1960 till i bought it in 1986.  Whatever was in them cases was so strong it would put my eyes and nose out everytime i would open them.

Maybe this can help date the scope...

But the scope could have been made well before the shipping date.  I would guess it would have been made around 1958 sometime.

The focuser knobs look exactly the same as the U152 used as a prop in the Dennis The Menace episode “Innocents In Space” that originally aired on Halloween 1959.

I kind of figured that was the date of the scope by the way the knobs and some other parts looked.  The address confirms the date even more as Unitron was at the milk st address until 1959.  Also the date is February 1959.   Awesome facts here.  There sure is a lot of the unitron scope on dennis the menace season 1 episode #5. You can watch the whole episode if you got Amazon prime.

That scope shown in that episode is just like the 1954-55 M160 i had. The focus knobs are solid and smaller and the focuser is the pre Super focuser version, also the counter weight shaft is smooth and it has the much bigger RA knob and also all metal SLO- MO controls as well the no ears 100mm lens.  So that scope is the older version. Odd that the RA gear has holes in it while mine was solid.  Also a big blooper in that episode as it would be hard to track the sun the way the scope was set up with the polar axis facing it.

 

But look at that pretty black paint on the mount and how it shines. If we could only go back in time and buy these scopes new.

I think the paint just fades with time with scopes that have been used in the weather or left in the sun. That M160 i bought was really rough and was left on a back porch for like 30+ years. I had to have the tube painted and the black had really lost it's luster.  It was a heavy OTA with the two tube weights inside.

Any mount you see that has holes in the RA gear is a very early version.  same is true for the 142 mounts.  Only the early versions had holes in the RA gear.   Which might date Rolo's 160 to the early 50's.  It could be the package with the 1959 date was something that was bought later.  What does the lens cap looks like Rolo?

All the caps are white plastic with Unitron in red.

So it does not have the metal cap that looks like a lid for a pot.   That makes it a bit later in the dating.  I am still under the strong belief that Unitron filled orders from items that were sitting on the shelf.   I doubt if any of the systems they sold came from NS shipped as a completely system.   They came shipped as an OTA, mount tripod and so forth.  Then as the orders came in they would assemble the system to however the customer would order their scope.  This would also explain the difficulty in dating the scopes from the focusing knobs.   Focuser are easy to change because the ID of the tube never changed.  So if one would want a deluxe focuser it might not be from the same date as the OTA was manufactured.  I have a 160 with the electric drive that sits on the shelf.  A lot of parts came still packed in the original box from unitron with the part numbers on the box.   We a clear indication that this system was put together with parts from the shelf.  My trips to Unitron over the years while they were still active revealed plenty of parts on the shelves from which they could fill orders.

Here you can clearly see the holes in the RA gear on the U-152 mount from the 1959 Dennis the Menace episode:

It also has a thick metal cap with a plastic wheel that has two different size holes. Looks like it may be for solar observing.

Also, Mr. wilson’s 152 scope (on the Dennis The Menace episode) has the white metal dustcap with the solar aperture stop and the rotating hatch door on the inside of the cap to close the solar aperture. Those white metal dust caps are very rare. My 152 that was a bit later still had the holes in the RA gear but it had the black plastic cap that followed the white plastic caps. My 142 mount also has holes in the RA gear (and the fixed clamshell rings). It seems to me that the holes in the gear went along with the fixed clamshell rings. I think that changed after the 50s.

What I haven't seen before and cant find in any of the "classic" catalogs on line is the partial dec gear. It has both the dec gear and the dec slo mo rod.

I wonder it that was a feature peculiar to the Photo-Equatorial models? Kind of like a tangent arm; used for tracking/guiding during long exposure photography?
