I would not guess that this gun is a two pin ventilated rib gun. A 28" vent rib is a rare and unlikely factory item. More likely is a Simmons retrofit field grade gun. My guess is a Simmons rib, misaligned at the extension, hard to solve that problem. If the starting point would have been a nice two pin vent rib gun, the value would be much higher. Pachmayr donated guns are not a hot item on the collector market. There is no real shading in the engraving background, just punchdots. Has anyone seen a pheasant looking back at you on the flush? Overall, not a very neat gun.

The Winchester Ventilated Rib (aka two-pin) was only manufactured in 12-gauge and two barrel lengths -- 30-inch for Trap Guns and 26 3/4-inch for Skeet Guns. One would have to machine posts on the barrel in different locations and then machine a rib to match to make a 28-inch barrel.

It's not a two pin, but of course we would know that if we had a picture of the top of the receiver.

Thanks so much, gentleman. I don’t know enough about these to know what to take pictures of. However, I’ve learned enough from your comments to understand that I should pass on this gun.

Again, my sincere thanks!

Brett
