Thanks, John. I am not fortunate (or unfortunte) enough to have a folding stock M1. I think an original folding stock alone would be worth more than one would have to pay for the full-stock rifles now; shades of Errol Flynn in Back to Bataan.
Mine are the full stock versions.
Thanks very much for your follow up message.
And I agree with your disclaimer, no matter what advice you have offered, any action I take or don't take is purely in my hands.

Thank you again.
