I had a Francotte bent by a well known 'smith in Texas about 18 years ago. It sprang back w/in months, and was not damaged. I didn't send it back as it took over a year and the intervention of Bob Brister (who recommended him in the first place) in my behalf to get it back on the first go around. I wasn't about to send him anything ever again.

I know of others who report high success with a bend.
