I recently bought a Smith M29-5 Classic Magnum II. It has a full lug 7 1/2" barrel, unfluted recessed cylinder, RR front sight. BFF prefix. Does anyone have a production date and relative value for it? It is basically unfired, no box, slight wear marks from carpeted safe.

I bought it to shoot, do not do safe queens, but the more I look at it, the odder it gets, especially the 7 1/2" barrel.
