OK, 177,741 has the screw.

Steve,

The records don't show when Parker changed the design of the firing pin on the SBT. The Parker Story shows 185608 with the screw on the right side of the frame to access the pin and that was 1919.

It would be good for the Parker Pages First & Last Found section. Latest S/N found for a SBT with screw access to firing pin.

I used to own 180115 SC SBT. A 32" straight grip gun and it had the screw.

Thanks, Chuck. Just what I was thinking. Further testament that great minds do occasionally think alike...LOL. I had always believed that access screw was there when production started in 1917. So much to learn and hopefully, lots more time
to do so. Thanks-----S

Your gun is an SC and as someone has posted it is an early one. I have a similar gun that is also a 177 number, so mine is your gun's sister. (Aren't guns female?) Mine is set up just like yours, but had a silvers pad which I replaced with a new one. I've posted pics of mine here before. I'll try again. http://i200.photobucket.com/albums/a...hotguns139.jpghttp://i200.photobucket.com/albums/a...hotguns001.jpg

My SC has the firing pin access screw on the upper right side of the receiver when you are looking down the barrel. I'm not looking at the gun, but I think the S# is 177128. I'll have to check. No pistol grip and a very nice piece of wood. I shoot it all of the time. It is about a 70/30 gun. The original owner was a famous businessman of the era and lived in San Fransisco. He probably shot at the Bohemian Club.http://i200.photobucket.com/albums/a...hotguns149.jpg

Its got a pretty serious chip missing at the wrist along the lower tang.

Steve: I took the pictures of my gun about five years ago, and they aren't very good. I'll take some more so that you can match my gun with yours. I suspect that they were made by the same smith, and the two guns are closely related.

Have you shot your gun? I've shot thousands of rounds thu mine, and she is no worse for wear. When I bought the gun it had a worn spring in the opening lever and a very badly worn butt pad. All fixed now. It is great to have such and wonderful old Parker to shoot.

I just checked the S# on my SC. It is 177853.

I know this is an old thread but I just read it. It is my understanding that most of these guns were CH grade. Mine is a CH and the barrel length is 34". Mine was produced in 1918 from the serial number and has been restored.

John, just to be technically correct, you have an SC grade (grade 4) single barrel trap gun. The CH grade (grade 4) is the terminology for a grade C hammerless gun without ejectors. With ejectors it would be a CHE hammerless gun. The SC grade with a 32" barrel was the most common configuration.
