New user/ Trying to ID a Parker Bro. SXS 12 Guage

[Autumn Daze]

Some early lifters with the "No radius frame" were prone to cracking and were rebuilt at the factory with the new radius frame design. I would think that Parker would have serial numbered the new frame to the original barrels but maybe this is not the case.

A research letter will not do any good to explain this. The order books show two separate guns made, not a repair to replace the frame.

Thanks for the link for disassembling my shotgun. I have it taken apart. I don't think it has ever been cleaned. Now the trick is to put it back together...

[Bill Sandefur]

Good morning. Thanks for you help with my Parker.
I took it apart to clean it and am having a hard time re installing the firing pins. Any ideas as to how to get them to line up with the hole? Thanks, Bill

[Bill Sandefur]

Thanks for your help. How do I tell if mine is the no radius frame or not?

[B. Dudley]

Yours does have the radius.
The transition from the water table to the standing breech is the area we speak of. Yours has a small radius at that point. Earlier Parkers are a hard 90 degree angle at this point.
Parker made the switch before your gun was made.

PM sent regarding value.

How common is this issue of nonradiused lifter frames cracking and are there any warning signs that are apparent by a visual inspection? I personally keep pressures and payloads low but who knows what these guns were subjected to in the past

[B. Dudley]

Any gun of that age is likely going to be fired with care these days and with he right loads.
I would not think cracking of these frames today should be of any concern.

Though cracking in this area my well have been observed over the years, I am not aware if Parker made the change as a precautionary measure or as a reactionary measure. That topic is likely subject for speculation.
