Normally, one can bet that the document was printed after the copyright date.

The copyright date has nothing to do with when the document was printed.




Technically this is true. It's the date the copyright is effective. Now, in the 70s (IIRC) copyright law was changed where you did not have to register a piece of property to enforce the copyright. In 1958, you did. The source material here would pretty certainly HAVE to be from 1958 (although technically it could be older, but never published).

It would be technically possible that Unitron could have submitted the copyright in 1958 and published it later (not sure why they would), but the documents would have HAD to have been submitted to the copyright office in 1958 to be registered.

OK, I supposed they could have elected not to file and just put the copyright symbol and the words there (lying), but that doesn't make a lot of sense either.

I say it's genuine.

But the source material could not be from a later date.

I had a 1954 unitron 4' with straight letters.. it was 100mm on front lense to. I think straight letters ended in late 50's or early 60's

It looks to me like there was a brief period where they went to italics in the late 50's and then went back to vertical lettering before adopting italics permanently sometime in the early? 60's.

And in the end the love you take is equal to the love you make.
I might never look at another Unitron again if this is not settled soon. If only they had put serial numbers on them.

During the 50's and the very early 60's, Unitrons ads in S&T where very good at announcing new models or new model types. In Nov 1961 the back cover ad features the "new 2.4 in eq refractor w/ setting circles and optional motor drive". This is the type we are all familiar with. Except with a non bolt on cradle.



That reminds me of another unresolved item - when did cradles come in and bolt on via diamond shaped reinforced tube go away?

I see 50's S&T ads showing a "Model NS114" the old "cradle-less" way. Yet people claim to me 50's Model 114 that do have full cage cradles for the OTA, no bolt holes, and metal knobs.

Did they go back and forth on a lot of details like this over a decade?

The cradleless models were very early, circa 52-54; 55-56 they had cradles but the cradle was part of the mount; then came the detachable cradle by the early 60's.

wish I had dates on all my unitron gear. I could create a Unitron time line and take pictures. I have stuff all the way from the begining and to the very end. They got so cheap in the end that the focusers had sticky labels on them. The very early gear the tube bolted onto the mount. There was no cradle. I have a 75 mm Alti Az that bolts on. I have a 150 with the very early fork mount. I have some of the early 128 mounts without the setting circles. I have the different 152 mounts in where some have a detachable cradle and some do not. The early 128 did not use detachable cradles. The early 142 mount had cradles that were not detachable. Also the early 142 mounts had black setting circles as did the early 152 mounts. Later everything got stainless steel setting circles. however, some of the early 152 mounts had no removable cradles and stainless setting circles. And then the slanted letters. I doubt if you can date the slanted and straight letters from their publications. They most likely had stock photos that they used and only changed them when the really needed to.

I believe Gerald has a very early 128 in where the tube bolts to the mount and there is not cradle. Stargazer has a very early 114 in where the tube bolts to the mount. He is still looking for the mount. These were the very first Unitrons in the early 50's I have a 40mm that bolts where the tube bolts directly to the mount. Only in the very early Unitron catalogs can you see these scopes. However, I think it is only the very small bolted on OTA's can be seen in these catalogs. Not sure if I ever saw a 114, 128 or a 140 in these catalogs that bolted on.

I keep hoping someone has a Unitron catalog dated before 1956.

Researching 50's S&T ads tells the tale. They announce, then release models as they come available and feature new models. Also the accessories. The Unihex was first offered in late 1955, electric drives in 1961. Very interesting stuff. I have 1951 to 1965, a few 1969 then nothing till 1970, with a few into 1980's. Need to buy the CD.

I have a catalog / brochure that has the Needham address, which is the mid 70's. However in is full of photos and drawings from the 50's models.
The catalog dated 1972 has models I would call 1960's and still drawings from the 50's catalog. I once repaired and restored a 128 that came from the original owner along with the receipt of 1973. Slant letter, phillips screws, and a focuser that was bakelite not a casting.

Akman,
That's the first Unitron I ever saw around 1958. The 4 inch alt/az. Owned by a rich kid who sold me a Sears 60mm which actually was pretty good. That 4 inch has always been in my dreams.
Bill

I was looking thru a 1955 S&T, and Unitron was announcing the winner of the name the eyepiece turret contest. The winning name was UNIHEX.
