Single Trigger Question?

[Josh Loewensteiner]

I recently picked up a very unusual Parker DHE 16ga. The gun has a single trigger, the likes of which I have not yet seen. It has the selector in the safety with a small toggle for right or left. The barrel can only be switched when the gun is in the "fire" position. The gun is a very lightweight 28" 0 Frame gun in the 137k SN range. I am at a loss for the name of this system or who may have invented it. Please let me know your thoughts on this trigger. Thank you in advance!

Very interesting - I've never seen that one either.

And it looks as vintage as the gun. Very cool.

[Brian Dudley]

That is very cool. It is very much like the single trigger selector/safety used on many modern guns.

You gotta open that baby up and see what is going on inside.

[Jeff Kuss]

That's a new one on me.

[Dave Noreen]

Not in my notebook of vintage single trigger patents.

[Bill Murphy]

Looks like a Beretta selector, maybe some kind of modern retrofit with a bit of aging. Brian is right. You have to look inside.

[John Knobelsdorf II]

Please show the trigger too.

Was it a Parker Bro’s. single trigger to begin with? So only the safety selector is a retrofit? Or was the trigger also modified (from double to single)?

This may not be illuminating, but will make me better informed if I ever come across another that looks like this example.

Also, what era of manufacture? Before or after the 1917 redesigned safety slide was being installed? I am guessing it is post 1917 by looking at the other details (like engraving style).

Josh , New to me also! interesting, Gary

[Bill Murphy]

Yes, please show a picture of the trigger blade itself.

[Brian Dudley]

The Parker Single trigger mechanism’s selector would not allow for it to be operated like that up on the safety.
This gun has certainly been converted after the fact to a different style of trigger all together. Like I said, one of a more modern design. That style of selector is very common today on many O/U shotguns.

[Josh Loewensteiner]

The gun appears to have original wood finish and barrel blue. It's an older recolor in factory style. These are the photos I had handy of the trigger and I can get more if needed. Thank you for your assistance.

[Dean Romig]

There appears to be some kind of alpha-numeric stamp on the right side of the trigger... unless my iphone is playing tricks on my old eyes.

I have a parker d grade hammerless with a odd ball trigger selector..it is on the left side of the left sideof the opening lever..on the left cheek panel of the stock..it pushes back and forth like the safety to choose the barrel you want to fire...to deep in the tomb to take a picture right now...my barrel selector looks nothing like this one being shown...but I have never seen another one like it...I like this selector being shown...you could choose whitch barrel to shoot in a hurry..you canchange barrels on mine in a blink of the eye..i have 2 lc smith with the hunter one barrel selectors a bird would be out of range real quick using those selectors...charlie

[Brian Dudley]

Dean,
That looks like the serial number on the trigger you are seeing peeking out from the slot.

This gun was a Double trigger gun originally.

Charlie,

That sounds like an infallible trigger in the gun you have. The selector on those was up on the left side of the tang.

[Dave Noreen]

Charlie, your trigger sounds like Alfred Harvey Worrest's Infallible Single Trigger as produced by his Lancaster Arms Co. Briefly in the teens Ithaca Gun Co. offered the Infallible Single Trigger on their Flues doubles.

Parker Bros. may have also used it a bit, as I have seen a 1913-vintage Parker Bros. Walter King letter to a customer where he says "As to your request we have removed our infallible single trigger, and installed the double trigger system."

[charlie cleveland]

I just looked it up by the pictures it is for sure infallible trigger system...charlie

[Alfred Greeson]

Good work guys, I continue to be amazed!
