Today I was at the local gun shop to pick up supplies. He had a nice Model 12 for sale that had WS-1 stamped on the barrel. It had a milled rib. When I asked what the barrel lengths was, he got out a tape and when we measured it, it was 24". The gun looked original. But I couldn't figure out the 24" barrels. Anyone ever seen one? Could it be a special order. I didn't really look at the serial numbers that closely, but I seem to recall when I glanced at them it was 779,xxx something. What do you guys think?
