Marked "No.1 JAS.V.HOWE PHILLA. PA 1922" serial number marked 172154 over 3

The serial number on the receiver dates to much later, It looks like someone found a .400 barrel and had this made up. 172154 may have been the original serial number the barrel came off of. I wonder if the original low number receiver wasn't replaced with a high number?

The original stock it seems was broken, When I got the gun it was in a clunky aftermarket bishop.
