Anyone have a clue?
 

It looks like a L stamped in front of the left trigger. Has anyone seen this on any other Parker? Would this have been something that a Miller trigger or Parker single trigger had?

L is for left or maybe it's the "Lucky" trigger or possibly it's just an upside down 7:D I just couldn't resist sorry:whistle: Did you get a letter on the gun?? :)

Possibly originally a single selective trigger gun and when the selector switch is in the rear position the Left barrel will fire.

Yup,I concur

O.P. you concur??? L is Polish for Right therefor if it's right that would make you wrong and we are back to L for Left or Lucky. How's that for concur?

C.O.B, don't be a smart ass:nono:

I thought you experts said you had to have the trigger plate swapped out when converting from a single trigger gun to a double trigger gun.

Just trying to educate myself::)

no sir not if it is a parker single trigger. miller yes you need a new floor plate or have to be a very good welder/ metal worker to get it done.
Parker SST to DT can be done on the same floor plate.

Dean,
I believe when the selector is in the forward position the left barrel is fired.

I agree with Mr Truitt with regards to a Parker single trigger guns ability to be converted to double triggers using the original floor plate. I have a 12 gage with double triggers that has the same L in the front and R to the rear of the left trigger and it definitely sports its original floor plate.

Why the L & R by the double triggers? The safety also has a R-S-L. That makes sense but why the letters at the triggers?

Chuck,Could this gun have had a Parker single trigger installed at the factory ie: L&R on the trigger plate then converted to a Miller single trigger ie: L-S-R on the safety. Don't know much about release triggers could they be selected to fire left or right barrels first?
