Thanks to all- I forgot to check the SN listing first. I loaned my copy of Peter Johnson's book on the Parker- but I thought he had mentioned the elimination of the top rib extension on the economy model around 1930. Also, this gun does have the Parker Bros. script style engraving on both side of the receiver, my question was, as later Remington graded Parkers often had PARKER engraved on the BOTTOM of the receiver, I wondered if they did that with the Trojan as well. The OV stamp on the barrel flats- was that used on all Trojans from 1915 through 1940 (aprox.) ??
I agree with those who proclaim the Trojan Parker as great shooting shotgun, no "frills" but that pair of ducks that were "dropped" whether by a Parker Trojan or a Fox Sterlingworth or later on, perhaps a Winchester Model 24- most likely weren't aware of the gauge or grade of shotgun that brought about their demise- the skill of the shooter and good gun fit nonwithstanding!!
