M73B1 Question

[bczandm]

I have a few questions on this scope. The numbers on it are telescope, M73B1 STOCK NO. 7579931 SERIAL NO. 33615 and the number on bottom 7635029 and a number on the right side of the adjustment plate 7669611. The serial number is not stamped on like the rest and looks like it was put on with an engraving pen. It not Weaver marked, I am guessing it is a type 3. I am interested in buying it and want to make sure that it's not a more recent manufactured copy. I am also wondering what the proper base and rings that should go with this scope. I'd like to put together a correct vintage 03a4 and can buy the scope for $700 I think. Is this a good place to start or should I pass on it?
Thanks in advance,
Bob

It appears to be a legit Type 3 M73B1 scope. That said I'd like to see another pic of the Data Plate showing the engraved serial # and the roll markibg on the scope tube. Your post indicates you've done your research so for $700.00 I'd say. Buy it!

Here is the only other decent photo I have of it.

Surprised it doesn't have "Weaver" stamped on it somewhere......unless that was deleted on the later military scopes.....?

I am still learning about these but I believe the type 3's were made at the end or after the war and did not have the Weaver name on them. I'm not sure if they were made by Weaver or not. I hope to get more information/clarification here as I dont know these well and don't want to make a $700 mistake!

Bob - The scope is a Type 3 'Weaver' M73B1. The Weaver name was dropped after Weaver began full production for the Goverment contract. Production was entirely during WW2. Original scope base & rings can be found but are Pricey when found. (Think approx 4-$500 total). Rings are often seen on ebay and are the vertical split redfield rings. The original base is the hardest to find. Its also Redfield. The 'electro-pencil' serial # should be a five (5) digit # from about 20000 or higher. A 'electro-pencil' is like a mini-arc welder. NO vibrating marker pens were ever used!
The second picture is not clear enough for me to verify if the serial # is legit.

I haven't seen any M73b1 scopes alone sell for less then $800 in recent years and some I have seen sold for more. Original ones are always in demand. Ray

All variations of the M73B1 had the actual serial numbers applied with electro-pencil.

A small number of the "type 3" M73B1 Telescopes were manufactured by Frankford Arsenal.

Drawing (stock) No, 7579931 identifies the complete scope.
The other 7NNNNNN stamped drawing (stock) numbers identify specific components (data plate, tube etc).

In recent years several of this model had been found in the original GI packaging as made by Weaver. The dates applied by QC inspectors indicate early 1945 production suggesting that all these "type 3" scopes may have been acquired as spare parts.
That said they are correct for use on an M1903A4.
If the scope is in good condition $700. is a fair price IMO.

Somewhat odd. The scope in question just popped up on eBay today. Same picture as displayed in the OP's original post. Opening bid of $600.00, BIN $900.00. Maybe the seller read this thread.

Good observation Mike. (I think is the link to the eBay auction you speak of)
