Man,Thanks Bronk.Just whatI was looking for.Looks like some quality work.I want to my local shop and ordered an uncle Mike's just for the time being.When the A$$holes broke into my house they got my S&W Model 657 Classic Hunter.It came with a 6 1/2" barrel.This one I bought to replace it did not have a special designation.But it is 7 1/2" full lug and non-fluted cylinder.Both of these barrel lengths are not really typical of Smith.
