I'm curious as to why you think it's the wong buttplate? They came with a few different types over the years, as did Ithacas.

Yours looks as though the wood could have shrunk a bit so the buttplate could be proud of the wood, but it may still be the correct one. Would seem odd to have such a pristine gun with the buttplate changed. It's a looker for sure, nice wood finish.
