Parker Trigger?

[John Taddeo]

At a recent show I noticed a Dammascus barreled 20 gauge (G gun if I remember) sporting a single selective that the gentleman described as an "infalible" (hope I spelled it right)trigger. Where the selector was on top to the left of the lever. He had told me this company had been based in Pennsylvania. I was just curious if anyone had info on these triggers? I should have got a picture as my memory is terrible.

i have no info on the trigger but i do have a d grade parker steel barrels that has the infalliable trigger and selector..the selector is on top...one thing i can tell my safety has to be in the fireing position before you can select barrel of choice..wether this is correct i do not no... it is a single trigger with ejectors...i like the selector up top... charlie

The Parker Story talks about the Infallible Single Trigger.

Infallible single trigger installed by the Lancaster Single Trigger Company, Lancaster, PA. It is a great trigger that usually works. If you fire one barrel and open the gun, the next barrel will fire when you pull the trigger next. If you want to fire the right barrel after firing the right barrel and opening the gun, you have to change the position of the selector switch. Odd mechanism, but it is what it is. I have two and they both work, even though they are 100 years old. If you can give me contact information on the seller, I would appreciate it. Thanks
