The gun is a FW and the stock was not a problem to fit at all.
The gun is 1939 and the serial # on the stock matched up to a 1946. Elsie held their tolerences pretty good in this case. I was surprised how easy it was to inlet--I am now going to glass it and make it fit like a glove.

The wood/checkered spacer sounds interesting--anyone else seen this?
Thanks for the input guys I appreciate it.
