Property number
Jim,
That’s a lengthy subject.
U.S.Express had several contracts. If we are specifically talking about Smith & Wesson double actions then both are correct.
They purchased huge numbers of double action Departure models on contract with two Major Distributors that I have tracked.
Some of the contracts like the OP’s gun have the serial number stamped deeply on the frame or sometimes on the barrel followed by a second “Property stamped contract size number “ elsewhere on the frame. That number represents a numerical size of the order.
Example : 175685. 3465
The 3465 is the actual number of the gun in the contract. So that contract actually reached 3465 guns. Some of the Express contracts were huge and spanned many years.
Other contracts did not have that additional number which from my survey represented a smaller order usually 12,25, or 60 guns.
It’s also very possible that the additional number was stamped at a later date that represented an inventory number of the total pistols turned in prior to our entry into WWI.
I personally believe based on the matching die stamps that they were numbered at the same time as a continuation of the contract but either position still represents huge numbers of pistols over about a 30 year span.
So the OP’s gun is likely the real deal but a very late and small contract that’s like near impossible to prove legit unless you find more of them. Good luck with that.
If that was my gun I would most definitely get a factory letter. Make sure you tell the historian on your form that you believe it’s an express gun and that you need to know where, when it was shipped and how many guns in the shipment.
This one was likely a small shipment possibly to Chicago but not necessarily.
