Great looking mount box. Did he make that just form pictures or did the carpenter have some measurements to go by?
Thanks. A combination of pictures and using the mount itself for fitting and sizing. I'm leaning toward not varnishing - maybe just staining the outside. I also will be using felt to cushion the mount and under the weights. This box is really for storing, I will not be shipping the mount in it or anything like that.

Impressed with D&G and the cleaning, just need to be patient as this took 2 months. Barry was able to get almost all of the white "ghosts" off. I can see coating losses from presumably prior poor cleanings, but overall very nice for a 50+ year old lens. Don't you love how the camera shows those tiny specs of dust?

Nice looking lens. soon you will have more 4" scopes then you know what to do with. Maybe a binocular Unitron is in the future plans
Thanks! I spoke with Barry at D&G this morning. He said the lens tested out very well. He did say there are a couple of residual spots he did not get off because he was afraid he would then have to refigure the lens with too much polishing. He prefers to keep the old Unitron lenses as original as possible if the quality is there. He also told me DON'T mess with the small screws in the front, just use the outside large screws for collimating.

I'm drooling over this instrument! Looks GREAT!!
I said it before,but worth stating again An original assy. of mount and OTA from the late 50's to early early 60's is pretty rare to find.

Let me check my parts bin. If I have them I will send them to you. If all else fails you can get similar looking screws and tap new threads into the mount. I have been looking into making my mini mill into a CNC mill. It looks like the parts cost more than the mill cost me. However, it will enable me to make a lot of parts and also these very unsual threaded parts. I have so many different mounts and I was almost mystified how many different thread pitches I found even between the same model mounts.

Have you tried Metric and Multistandard Components Corp.?
They have both an amazing selection of those "hard to get" items and sell in small quantities. Large selection of different head sizes, pan, cheese, cross, etc.
I have been using them for decades and highly recommended them. They also have a selection British Thread items, BSW,BSF, BA etc.
