Don't fear- I needed the clarification. I noted a numebr of early actions/barreled actions going to Merkel, Sauer, etc. in Speed's book; when I've seen these rifles for sale, however, I don't believe I've seen any that had the WFM roll mark and/or serial numbers that appear to be "right" for factory Mauser production.

Maybe I'm just trying to "wish" this into being a modified factory commercial piece, but one of the things I latched onto in the conversation with the seller was the WFM roll mark and serial number range on the barrel shank & receiver.

I'll happily post some pictures on receipt so you guys can help me figure out what it is.

EDIT: I asked the seller to send me a picture of the peep sight before he boxes it up this afternoon. If he delivers, I'll post it here.
