Tom. I am sure there are some fine gunsmiths in the Badger State. When I served in the USMC several of my buddies hailed from Rhinelander, and LaCrosse. My gunsmith, also a PGCA member and devotee of The Old Reliable, may have the parts, and has redone many Trojans, several of which I have seen and shot. He is working on an older (1903) GHE 12 for me now.
Contact Brad Bachelder- 616-459-3636, e-mail at bachelderfirearm@ aol.com. His summer hours are Tuesday-Friday 1000 hrs. to 1700 hrs. EST.
If you are observant enough to spot the rib extension difference in your Trojan Parkers, you may have also spotted the lack of the letter Sierra (s) in his e-mail. I tried to reach him at
bacheldersfirearms@aol.com, which Won't Work- use the intel in the second graph and you'll be "spot on". His wife Lori, who is the Ops. Mgr. explained that to me.
By the by, I had a 12 gauge Trojan for many years as my pet pheasant gun.
28" barrels choked Mod and Full, DT, standard stock and black buttplate, made about 1926-lotsa wear and tear but what a great shooter. I bought it about 20 years ago for $375 if memory serves, low price mainly due to someone having written their full name, rank and sn on the bottom of the receiver with an electro-etching stylus. Sold it about a year ago to a hunting pal who always wanted a Parker, and the GHE 12 will be its replacement in days to come. My former Trojan had the small rib extension, not the Doll's Head shape as on my GHE-
Perhaps it was the introduction of the Model 21 in aprox. 1931, that had no rib extension at all, that prompted Parker to delete that feature, perhaps it was cost reduction as the Great Depression was afoot. I had also read somewhere that Parker designers had planned to eliminate the Doll's Head from the graded guns, but Sales and Marketing thought too many Parker owners extant relied on that design, almost a Parker Trademark, as the recessed hingepin design. Someone also once suggested that Winchester had tried to buy Parker Brothers Co. in 1926, and when their offer was graciously refused, went ahead with the design of the M21. Just rumor!!
