I would not call myself a collector yet but I do have several of these single shots. None are for sale at this point. I just bought a 28 gauge and a 30-30 at an auction, along with a 20 gauge barrel. The 30-30 barrel is grooved like a 22, have you ever shot one set up like this. I have a burris set of rings and it has stayed in place so far. I have one 16 with a semi bevertail forend, cheek piece stock and etched engraving. I have another action with engraving on it's bottom surface. What do you know about grades and models? If I decide to sell any of these I will let you know. I do not have a 32-20 or 25-20 and am looking for either. Shotgunner
