Hi and welcome to the Forum.

S885679 would indicate probable shipment in April, 1947. A lot of them in the S88xxxx range shipped that month.

As noted, this one has been converted to a target revolver, rather inexpertly I would add. That hurts the value but makes it a sort of interesting gun.

The stocks on it are later, being the style used from c. 1953 until c. 1967.
