[Old and Reliable]

All very informative replies indeed. Without getting into the Fox gun arena here, perhaps the Trojan with the small rib extension, no matter what name properly describes it, as Parker's economy gun, competed for market share with the Sterlingworth, the LC Smith-Hunter Fulton, and later the Ithaca/LeFever Nitro Special.

Of all these "economy" based doubles produced by major double gun makers, it is my understanding that only the Fox Sterlingworth had the option of selective ejectors. I can now see why Parker didn't offer that on the Trojan model- A grouse hunting pal has a later Ilion mfg. Trojan 20 bore, plain breech face as on the M21, and a Miller single trigger. Nice bird gun indeed.

In Paul Curtis' 1934 book "Guns and Gunning" he discusses the doll's head in his chapter on double gun types, but if he mentioned the Model 21 therein, I missed it. By increasing the length from the standing face to the knuckle-or hinge pin, the Winchester design team added strength, but also extra metal, hence a heavier gun. Fine for the duck blind or goose pit or pigeon ring, but perhaps a tad heavy for an all-day hike after wild flushing Roosters in SD.
