Help with the DOB of a 10-5

[rjencks]

My uncle just recently picked up a 10-5 with a 6"bbl and is wearing combats.
Mechanically it is great, but has a good amount of holster wear on the left side, along the barrel and cylinder. Legend has it, that the original owner was Boston PD.

The serial # is 05635

Any help with the DOB is greatly appreciated.

I believe that's an assembly number from the yoke cut out.

The serial number is on the butt of the grip frame and should start with a letter, for a 10-5 likely C or D.

could you please re-check the serial number on the butt. A Mod10-5
usually has the letter C or D before the number. Mike 2796

You are correct, that is number is from the yoke. I will look on the butt and update the thread.

Thank you.

The serial number from the butt is : D138904

Thanks again for the help.

If it's a Boston PD gun it should have B.P.D. with numbers after, stamped on the backstrap.
