Per Parker Gun ID and Serialization, it's a Parker trigger.

Send a pm to Ken Waite he is coowner of Miller Trigger and a lifetime PGCA member, his shop can fix your trigger and know what they are doing!

In most cases, a single trigger on a Parker is a Miller Trigger replacement. If you have a Parker with a Miller trigger that needs cleaning or repair, you will be pleased to know that the Miller Trigger Co. is still in business. Their contact information is: Daniel May or Kenneth Waite III, their Shop Phone is (315) 626-2605 and their Cell is (315) 529-1518.

This information was accurate when entered here on December 2011.

Thanks Robin, didn't have the contact info at hand, but they work on both Miller triggers and Parker single triggers.

i bet brian dudley could help with thestuck selector....charlie

Kenneth Waite and Dan May fixed a Miller trigger for us too

I sent my Parker 28 Gauge DHE up to Dan at Millers and the turn around was fast and the Trigger worked like a dream ,Highly Recommended ! Too bad I never got used to those long barrels on a small bore and ended up selling it !

I am not so sure you would have to have the ribs removed and relaid if only a small bit of solder is missing now due to the heat gun. A good gunsmith may be able to fill/fix the void without further damage or work required. There is paste designed so that it does not transfer heat to the other solder and Brownells also sells solder that has a much lower melting point than standard solder; comes in sticks. I have used it on the ends of barrels where the solder was missing with good results.

Now I'm getting somewhere. That was going to be my approach when I find the right person.
Thank you
