Lets compare the #2 on the 1st American serial #1025 with the 3rd digit in the OP's pic which is assumed to be #1429.

There is no way is that a 2 on the OP's pistol as the loop is no where near round and deep enough - its a 3 instead meaning that's not #1429 but #1439 just like I said above.

Pates book list #1439 as a known US issued 1st American but NO SURVIVOR INFO is listed meaning the OP's pistol could very well be a closet find

So much for jumping to conclusions and making assumptions...
