Late Remington VHE Grade Parker, probably made or finished in Ilion, New York. PGCA letter could possibly (not likely) tell who the original purchaser was. The IBM cards, the only provenance normally available in this later serial number range, sometimes gives customer information, more often does not. Check on the link on the PGCA website under "research letters" to see if they have information on the gun. Quite a coveted variation, 16 gauge Remington gun with single trigger.
