Sounds good.
Your text: "Seller is asking $1150 and describes it as "Appears to be numbers matching in all the places you expect.'" put me off to be honest. My immediate response to the seller would be " IS it matching or not?? You should strip the gun and find out for yourself before selling..."
If you walk away you have lost nothing. The right one will come along. For myself, a shooter should be in good shape without a lot of visible damge ie. pitting, dents, rust, etc. Of course any shooter should be sound and fully functional.
Anyway, I look forward to the next installment in your search for a good shooter
