I started the discussion on this thread:
starting at post 8310
Found this, my first Unitron, 50 miles away. The gentleman that I purchased it from won a bid on a storage unit and found this inside. He said the storage unit is still crammed with items and he is only about 1/3rd way through it. I am hoping he will find the legs and the mount that went with this scope. We agreed that if he finds them I can have them for no extra $ from what I have paid for the OTA. I will start a separate thread as I need some Unitron experts to help me out. This OTA is very heavy. I believe it must be brass with maybe weights inside the tube at the focuser end.
To keep from cluttering up the previous topic I will start here with what I found and my progress. Already received help from several members on links and possible dates. Although I would like a more definitive date of manufacture, fully understanding it can be impossible to get an exact date.
Besides looking at the Lens with no markings and the tube itself having weights inside and being of Brass instead of Duralumin what other clues do you look for to assign a possible date or at least a built before date?
Can the eyepieces give a clue? The lettering on all the eyepieces are Gold in color.
