The same man that I bought the Trojan 12 gauge from- also has a nice 12 DHE- 30" Titanic Steel barrels, DT- solid red Silvers pad with plugs-restored by the Del Grego Gun Shop about 22 years ago not shot since-- the serial number chart on this Forum shows it to be a 1906 year of manufacture- it does have the angled tool steel wear plate pinned into the barrel lug- I am just curious- given the same condition- what would this gun be different in mechanical features from the same DHE 12 made in (1) 1916-- (2) 1926 and finally, 1936? I have read about changes in the number of action parts from 18 to 4 over a period of time- also, were the ejectors always of the same design, or did that feature have changes over a 20 to 25 year production run? Thanks
