I've had two of them, in 12 gauge. Still have one. Used them for BP cartridge trap matches. They were actually made in all the gauges, including .410. Both of mine were marked Western Field. They came with a solid rib, schnabel forend and some checkering on pistol grip and forend. I don't think they were officially called trap models, though. They were made around 1910, from what I have gathered.
