The one that I saw was made by the old Harrington & Richardson Co, not NEF, but it was late enough that it had the transfer bar safety. I didn't notice what the SN prefix was. This one had the dull electroless nickel finish, not shiny. It was electroless nickel all over, barrel, baystate, the works. The wood was hardwood with walnut finish. It was in 20 gauge and had the Topper name on it.
