I had two older series Trojan 12's- std DT-and the small doll's head- a tad more drop than I like, but I worked around=- both dropped a lot of Roosters and a few mallards for me (before steel shot laws)-- I just looked seriously at a 16 Trojan this week- 28" barrels size 1 frame (std. I believe) and serial no. aprox 1929 mfg. it did NOT have the small doll's head rib extension, it was the later flat breech faced version (like on the M21)--
I'm really not a 16 man-love the 12's, but with the later stock dims-I could just see a few bobwhite quail dropped to a well placed shot over a fine Pointer or Setter- I ended up with the PH 16- 26" Twist barrels- I bought it (for quite abit less than the Trojan was listed for) as the top lever spring was broken- and the shop selling it on consignment had listed it as a Parker Trojan 16 with Unsafe to Shoot barrels- my good luck, as I have learned so much about those barrels and Parkers from this PGCA website-
The clincher, besides the unmarred screws and DHBP was the beautiful flame grained walnit and the unmarred or uncut stock- it is also on the O frame- and I may have access to a set of 28" 20 Vulcan extractor barrels on the O frame- that's a "down the road" option- always great to have a Winter bench project or two- isn't it?? Best--
