Thanks, Lobo, . . . I had thought the N frame was awful close . . . but never had a chance to compare as I have no source here for the 1917.
He's got the picture I sent him . . . he's doing a "measuring" of the different points of the weapon . . . and what I'll do is just make a wooden model . . . which will do for what we need done.
I had to do that a few years back for a model 29 . . . it was a "trial run" so to speak . . . worked out like a champ . . . the customer was thoroughly pleased . . . and I still have my pine wood "Dirty Harry" revolver in case I ever need to make another model 29 holster.
May God bless,
Dwight
