I guess only a research letter on the particular gun might mention that feature.

I think I'll have to scan the photo. I'll look tonight when I get home from the polls.

I found the pictures of the gun I thought had these gas vents but the shots I have didn't include them. I'll have to keep looking.....

Thanks all for your replies. Mark opines that the spring devices are to apply tension to the shell to keep it from falling out. That very well may be correct. Dave thanks for the advice on sending a photo. I reduced the size and attached it. I hope successfully.

Seems as though the photo did not go through. Any suggestions? The serial number for the gun is 88929.

Gordon, we highly recommend you send for a PGCA Research Letter for this Parker. You can access the research letter function from the PGCA home page.

Shell holders
 

I saw a gun at the Southern Classic in Georgetown that had the small spring- loaded devices that prevent the shell from faling out of the chamber. I think John Allgood had it. I don't remember the brand of the gun. This was the first gun I have seen with them. They were demonstrated and worked as intended. They have nothing to do with escaping gas protection. Cheers, Tom

Tom, can you describe how and where they fit in the gun in the closed position?

Shell holders
 

Hi Dean, They were approximately 1/4 to 3/8" from the rear of the chamber on the bottom. They would apply pressure on the brass portion of the shell. They were spring loaded and I think they could be adjusted from outside of the chamber with an Allen wrench to increase or decrease pressure on the shell. They protruded approximately 1/16" through the chamber. I just talked to John Allgood and it was not John who had the gun. It may have been someone who just walked by. And I do have a photographic memory but ran out of film ages ago. Cheers, Tom

Gordon - shown below are the picture posting instuctions from the FAQ section. There is more information ther, also

Thanks all for your responses. I am not sure what happened when I edited the picture as advised. I can not now access that picture in my documents. It comes up the same as shown in my attempt to post the picture above. I have tried again to attach a JPEG photo exactly as suggested by John Dallas and each time the upload fails.

Tom Carter describes exactly how the gun is configured. I did notice what appears to be Allen screws located under the extractors.

I plan to request a research letter.
