The seller misread misread the name on the clock drive, it's A. W. Haydon. A. W. Haydon was a clever dude, if interested check out his Wikipedia page. One tidbit: he sold his company to Phillips for a cool $1 million back in 1951, when that was a lotta money.
This scope looks like another one that was kicking around here on the classic site not so long ago...but maybe old scopes like this look more alike than not.
The old man and I went to see this thing. It is a home brew item. The axle shaft housings were made from welded aluminum stock. The OTA was aluminum pipe with end rings. The focuser is a standard Edmund 1-1/4" focuser with white knobs instead of black. IF we remember correctly, Edmund had white knobs for a while but switched to black in the early 60s. (Correct us if we are in error.) The finder was something from scrap pieces with a homemade reticle illuminator. The rotating saddle and saddle plate were definitely handmade. The clock drive is seized up solid and the RA cannot be turned. The tripod is from some anique something or other that we could not identify but, it was definitely not from an optical instrument. The rest of it was just odd parts bolted together.
(He told us he used it on Mars last night! It was raining and Mars is still close to the Sun! Hello!?!)
The fellow was somewhat brisk after we made a fair offer which was far below his asking price. However, after time, we learned that he got it from NYC. The mirror measures about 5-1/4" - 5-1/2". Everything we saw and learned tells us it is very likely a project scope from the days when the Hayden Planetarium was having telescope making classes and such. The power plug, the assembly of all kinds of mismatched parts all points to that conclusion. In short, it's worth maybe $100 - $125 MAX!
Anyway, he claimed to have someone send him and email wanting to buy it at full price. Maybe. Maybe not.
