I hope this helps your sale. I bought a surplus Mdl 10 pre-CoVid and sent it S&W to be reblued. They did an excellent job, it took 3 months and cost $295.00. The gun is like new now and it’s pinned and recessed so it’s only going to go up in value. If I didn’t already have one I’d grab yours up A.S.A.F.P. GLWS
