I wasnt really looking for another but someone was selling their collection and offered it. It has the earlier metal trigger plate and still had it's original box which was appealing to me. I thought I'd put a spare used steel breech on and a fresh pump cup but the thing has turned into more hassle than it's worth.

The pump handle closes but a little loose, I thought it would just need a new piston pump cup. Opening it up I found a standard piston mating up to a flat top valve
Once the barrel was off for inspecting and cleaning I found their was no rifling. I tried cleaning hoping it was just heavily fouled clogging up the grooves. What was the owner feeding it?
The pistol had looked so original but you just don't know who's been inside.
