With that WMR cylinder that is a rare piece. That would have been a special order as a LR cylinder was the "standard" extra cylinder. The purple is the result of a chemical reaction in the blueing. Not common in S&W's but not unknown. As you have described the basic gun, without the box and doc's I would guess $800-1000 in today's market. I don't know how much extra the WMR cylinder would add. Probably $200-250. Prices are a little crazy right now and I am being a little conservative.
