Buttplate ID ??

[painter777]

Bob, I think your best view is your 1st post. It's like the 4 inner dimples in the corners aren't visible in that picture (but they are there) by appearing not being there it looks like a square pattern between the dimples. Compare that plate starting with the very bottom row with the one I pulled from the CCCF. It matches up exactly right down to the slight partial dimples on the ends. Looking at the inside will give you the best view to compare to.

Any bets on Dover???
