We need pictures of the trigger to determine whether it is a Parker trigger. We need pictures of the rib at the muzzle and the muzzle face to determine whether your gun was originally a 26" gun. Some aftermarket triggers are not that much of a detriment to a well used Trojan.

Just the fact that the gun has a rosewood grip cap makes me want to wager that this gun is heavily altered from its original configuration.

working on pictures as requested. May take a few days. Thank you to everybody for trying to help me.

OK, here are a few pictures for your review. Hopefully these reveal some info to help determine the guns lineage. Thanks.

I don't know anything about single triggers but I think that one is not original based on those two little pins.

Stock not original, Barrels are cut and the single trigger is not original.

Someone made a Trojan Skeet Gun. Replacement wood, probably cut barrels and probably a Miller single trigger. We need a shot of the safety slide on the top tang to see if it is selective or not.

When the Trojan Grade was introduced in 1912, it was offered in 12-guge with 28- or 30-inch barrels and only 28-inch barrels in 16- and 20-gauges. The first catalogue that I have that includes 26-inch barrels for all three gauges in 1923. The only catalogue I have that shows the option of a single trigger on the Trojan Grade is the 1937 Remington-era catalogue.

The safety does not have a barrel selector.

I made a verbal promise to the man who gave me the gun that I would never sell it and that it would go to my son upon my demise. I am assuming since the gun has been heavily altered it does not have any significant value? Maybe a couple grand tops?

Regardless of what cash value it has, it's an unusual and interesting Parker and will likely shoot as well as any Parker worth 10x as much and should make a great skeet and grouse and woodcock gun in heavy cover. So, go out and shoot the hell out of it and be proud of it. I sure would be.
