Sorry, I think he is fishing...I'm probably wrong but my gut says no, he's fishing

Looks to me you have a standard Flying Geese circa 1915 Catalog without a inserted price sheet which would have been dated.Therefore it is nearly impossible to tell the exact date, but others more knowledgeable may disagree. It would be in everyone's best interest if you did not sell your catalog off line, the right thing to do is join the PGCA and sell it in the classified section of this forum. You will get the best price and you have already received $45.00 in free information and advise. Craig

I agree with Craig Larter's conclusion that it is a 1915 catalog. Craig (the poster) states the A1 Special was $400. I just reviewed A1 Special prices from the following; 1911 pocket catalog = $525; 1912 pocket catalog = $393.75; 1913 pocket catalog = $393.75; ; 1915 catalog = $400; 1915 with 1916 price overlay =$400; 1916 pocket catalog = $400
In addition Craig E's catalog shows upwards of 170,000 guns in use with a career of over 50 years. Production of Parker shotguns reached 169930 at the end of 1914. Hope this helps

Thanks so much for your time Craig & Mike. I'm not sure what I will do with this, maybe put it in the gun safe for the grand kids.
But I will be adding some information with it.

You had best sell it now, not give it to your grandkids. It was easily a $650 catalog a few years ago, but now it is going unsold at that price on the Pat McKune ad you posted. One of our members posted its value in the $325 area. Sell before it goes down again. By the way, Pat's Parker offerings have always been a good reference, but, somehow, his stuff doesn't fly off the shelf, probably because his prices are at the top end of reasonable. Most serious Parker memorabilia collectors already own the items on his list.

Was just wondering what year the Trojan Grade first came out?

Trojan introduced - 1912
 

The Trojan Grade was introduced in 1912 as a $25.00 gun to compete with lower priced shotguns. First serial number: 159374
