Most often, the problem is accumulated crud and dried oil gumming up the barrel trip-- try this-- remove the splinter forearm- there is no release on the Parker Trojan grade guns, I use a long wedge of soft pine carefully inserted at the tip of the forearm-so as NOT to mar the forearm or barrels- then move the top lever over until the barrels are freed and pivot away from the receiver. Push down on the top of the barrel trip with a key or tip of a flat blade screwdriver and see if the top lever moves back to the closed position, as it should. Some CLP or crud cleaner might help--
I have receiver parts for a 12 Trojan if needed later on, alas, no stocks. The 12 Trojan was only made on a No. 2 frame, so there may be some stocks out there- try Galazan's- but you have to look under Novelty Stocks to find them, why that is so, I do not know. I have owned two 12 gauge Trojans over past 30 years, and the pheasants and ducks hated to see me totin' them afield or in the blind- they shoot as well as the A-1 Specials, and were made to be used- enjoy--
