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.
