Parker Knurled Triggers
 

Parker knurled/checkered triggers are unusual.

Notice how the knurling/checkering is contained within an oval border.

A few high grade guns have knurled/checkered and articulated/forwardly hinged triggers; these are only knurled/checkered.

Shit, I don't know if these are knurled or checkered. They have scratch marks on them.

Do you think these triggers are knurled, or are they file checkered? I don't know but would like to know how it is done.

I think they could be considered either checkered or knurled. If you look up the definition of knurled it describes what we think of as checkering. I have a WWII 1911 that has what I think are original triggers faces like that and I've been told they were 'checkered'. Take your pick. I've knurled things I've made on a lathe. There's a special took with rollers that upset the metal into the diamond pattern. The more passes you make the more they become pointed diamonds. so maybe if the pattern is pressed in, it's knurling and if it's cut in it's checkering??

Checkered.

Richard, I agree with your definition, and, Brian, I agree that the pictured gun is probably checkered. Knurling a surface like that trigger would be a piece of work.

Checkered triggers were also found on lower grade guns.Here is a VHE double trap.

Is that one of Danny's guns. ? :rotf:

Nope...Not yet

Correct me if Im wrong here but in rolled or stamped knurling no metal is removed, causing the peaks of ridges to be higher than the original surface as they are pushed into the tool from the valley. Cut knurling where metal is removed is flush to the surface.

I'd rather see Danny shooting it than Dave. Danny is a nice kid. Dave is a gun thief.

Some body bound pins are Knurled on the last .05" to retain the pin after it is tapped into a hole. It holds the pin but can be tapped back out as the surface area of the peaks is minimal.

It is easy to tell that these triggers were single file cut checkering and not done by an expert. The lines are uneven and of different depth. I am a little surprised that this was acceptable to Parker on a high grade gun.

Bill, I just checked my checkered trigger with a loupe and the work is done by a cut file. The spacing and depth is extremely uniform and in a border such as the picture Bruce posted. The quality of the work is what would be expected from the factory. My photo is not the best.

The 1904 CHE 16 went back to Remington in May 1939 and was rebarreled. I suspect its Remington work on the original triggers. The triggers are sized like Meridens and not like Ilion sizes.
