Unitron?

That's a Tasco 7TE mount. Nice unit. Not for that $$$. In that condition with no weight - $50 max.

Agreed.  Looks like my 7TE's.  $50 if you can use the parts. Might have been used by other makers but not a Uni.

Considering that it includes shipping, maybe not a bad deal but should be inspected or carefully questioned first. This version has a bad mount design that can not see about 30 percent (or more) around Polaris. The mount is not a proper GEM. ALSO, apparently many have found the secondary is on a short stalk that prevents normal collimation. I have two with no such issues, mine have the secondary in the correct position. Mine are both completely restored and one (or both) are part of a 3 model family group: the 4.25", 6" Dyna OTA on RV-6 mount, and 8" observatory bell pier Dynascope.   

 

Honestly it's a nice price delivered to your door if it suits you, as long as it's functional according to your desires.  HERE is a LINK to mine on CN.  

I would NOT sell my completely restored manual one for $200 local pickup, but mine also has a true GEM mount. My other one is factory motor drive and the dedicated family member.  Go to this specific entry HERE to see the difference in the mounts. The posted scope is like the picture on the right with NO Dec shaft or counterweight!!  

 

The difference is that the posted scope has no DEC rotation. It only pivots on the RA shaft. It is a bad design. I have this mount restored and boxed for posterity purposes.

For those looking for an authentic Moonwatch telescope, widely used during that program, here is one that appears to be in good condition for less than $60 delivered.

The M75C was NOT a Moon watch telescope! It was only one of many elbow type scopes used on WW-II anti-aircraft systems as well as heavy artillery. The M75C was used as component item by each anti-aircraft director for tracking in elevation and in azimuth. By tracking the target, the angular speed, present azimuth, and present elevation data were determined thereby determining just where the rounds were to be aimed. The telescopes were adjustable for focus with an adapter scale to adapt the focus to the user's vision. Filters were brought into use by turning of knob allowing the use of clear, amber, neutral or red filters.

 

They were not used in the Moon Watch Program. The other scope listed is one of the official ones that was used in large numbers in the late 1950s for tracking and plotting the orbits of satellites.

 

They do make really good right angle finder scopes if you can design and build a good mounting and alignment system for them.

 

I don't think that there are many here who are old enough to have used them on the original weapons platforms so, it's no wonder that no one really knows anything about them. I believe they were decommissioned before the Vietnam conflict. None of the people I've met who were there ever saw them in use and they were surplus products from Edmund and Jeagers in the mid 1960s which kind of proves that suspicion.

Addendum: Forget about this one. For that price my old man just grabbed it.

I asked and his reply was, what you SEE is what you will get, in nicer words than that.

 

Price of scope:$250

Cost of gas: $260

 

I guess it is too far away.

They sent me a discount offer, but I had to decline it. Someone closer may want to send them an offer.

So as not to detract from the purpose of this thread but rather set the record straight, the M17 elbow telescopes were officially used at Moonwatch stations: https://www.cloudyni...opes/?p=1233749.  Greg Roberts initially refers to it as an M8 elbow, but corrects the designation later in this thread when he actually inspects the M17 telescope that he used.  Furthermore, modified M17s were used to construct the legendary Apogee telescopes.  I believe the M75 is identical to the M17, except for the reticle and placard.
