1873 Trapdoor

Hi, I was wanting to get a serial number check on 1873 Trapdoor serial number 145322. Thanks

Frasca & Hill list 144471 at end of 1880, and 164848 at end of 1881. So 145322 would be approx. 2 weeks into 1881 production.
Caution: I am not quite sure if these figures refer to the calendar year or the fiscal year!

Thanks for the info.

Springfield Research Service has no record for your number but all around it went in service to units in the Spanish American war.
