I have a scoped 8 3/8" Model 657
When I bought it 23 years ago, it was already scoped and came with the holster.
Wish I had a picture with the rig. It is all several hundred miles from me and I have not had it out in quite a few years
I am pretty sure the holster was Bianchi. The model X2000 sticks in my mind. I might be there Saturday morning. If I remember, I will bring it back home.
