overload proved

Fritz Dornan · 05-01-2012, 08:54 PM

Hello Gents,

Looking at the photo you will see the overload proved stamp. Can some one can tell me the how the barrels that were overproved were conctructed differently than a set that was not overproved, and to what psi they would have been tested to? Does anyone know how common the overload barrel sets were?.Also what is the mark J.G. in the oval on the left of the bbl. flat.

Thank you ,
Fritz

All Parker barrels were overload proved, regardless of year. See TPS p. 515 for the service load and proof load tables . J. G. is James Geary, the Parker barrel assembly superintendent, also as explained in TPS. In the mid 1920's , around 1925, Parker began using the Overload Proved stamp, although those barrels are no different structurally or dimensionally than previous barrels. Both fluid steel and damascus barrels were overload proved. Proof loads differed by guage and were the industry norm of the day, including 15,000 psi for 12ga when SAAMI standards were established in the mid 1920's. Again, for details, see p. 515, TPS. I have on occasion posted photos of the service and proof load table on this forum. For example, for a 12ga, maximum service loads of around 10,000psi are given. A Parker owner need not look very far to find loads at or below service loads.

Proof load psi should not be confused with rupture pressures.

Most questions regarding the Parker gun can be answered by reference to The Parker Story.

Bruce, Thank you for your reply and another reminder that most of my questions would be answered in TPS book. I am looking for a copy of TPS. I have found a nice leather bound set but I will pass at $850.00 Yesterday a friend of mine gave me his extra copy of the Parker Gun Identification & Serialization book so that is a start. Will keep the questions to a minimun until I find a copy of the book for myself.

Thanks Again

Unless you want the limited set of The Parker Story,

As it has been mentioned here before that the Double Gun Journal has recently advertised "blems" for under $200, New sets for $295

you could also order here, i got mine from them and was happy with the transaction

That is true Fritz. The Parker Story is invaluable for anybody interested in Parkers. Most of the time, the answer is in there. I had Parker books by Johnson, Baer and Muderlak and got on the pre-publication list for TPS, eagerly awaiting first Vol 1 then Vol 2. TPS is so superior to any of the others that the others seem almost quaint in comparision. I don't mind and I doubt others mind, answering questions, but the response is in a sentence or two whereas TPS devotes pages to the issue. For the complete answer and background, always see TPS. A Parker enthusiast should also have a complete set of all Parker Pages.

As for citations, I don't want a reader to think that I am merely giving my opinion, so I believe citation to the authority ( usually TPS) is the best course. Backing with an illustrative photo or table is also helpful to dispel unfounded internet statements.

There are those old timers who still complain today that The Parker Story and the PGCA ruined Parker collecting because no longer could those fellows ( often dealers or gunsmiths) say anything they chose and have their opinions accepted as fact. Even today a person will hear all sorts of unfounded stuff stated as fact. TPS and the PP's clear the air.

Fritz, After you have devoured the wonderful tome called "The Parker Story" you will still have questions from time to time.Please feel free to ask all the questions you want. I for one am more than glad to help.

Thank you Dave,
I am indeed looking forward to reading the TPS this spring and summer and begin to unravel my own mystery of the Parker Gun. As you pointed out Bruce there is A LOT of folklore shrouding the gun and as a result there is also a lot of opportunities to step out of bounds so to speak and get yourself hurt. To me it appears that there has never been a Gun as varied and complex as the Parker Shotgun. It is because of its complexity, verified in the records that were kept, that it has held the interest of so many people who love the adventure and hopes of encountering something rare and unusual.
And for goodness sake it is a SHOTGUN what more could a guy need!!
