Wow, beautiful find. Congratulations

 

Found this today the Olympic barrel and Slide are mint. Not sure who made the grips but they are very comfortable.

You say it is a 1951 Supermatic. That would be the first year for the lever name design series and it continued to use the shrouded breach design and lever takedown of the previous lever letter design serisl. The lever takedown and ribbed barrel with cross dovetail front sight confirm the design series.

A 1951 would have come with the older finger style magazines which were never available in cadmium plate. These new Harry Swefreid designed lip style magazines were not availible untill early 1953 and then not in cadmium plated form. The magazine drawing Revision F dated 2/27/1954 was the change to cadmium plated magazines.

The 4.50" Olympic barrel is for a 101 design series gun which is the second generation past yours. If my obsercation is correct , it will not fit your frame.

 

Thanks for the information. You are correct the barrel does not fit. The pistol serial number is 357,5XX. Now on the hunt for a 101 second gen

 

Can't be sure with a partial serial number but I suspect your gun has a 1952 ship date.

 

Complete number 357589

 

Yur particular serial number is not in its expected location nor in the firsr report after that time. This indicates it is not earlier than January 1952, but the exact date cannot be established from what I have been able to find .
