Anybody had experience with the Holland single trigger. Looking at a Royal with the single trigger. This one allows you to push it forward and shoot the left barrel. But only that barrel as I understand.

Yup. You don't see them that often. I didn't like it.

From my copy of the 1904 H&H catalog, page 10, "Royal Hammerless Patent Single Trigger Gun", they clearly state that it enables the gun to be fired right-left or left-right, with the left barrel being fired first by pushing the trigger forward.
If you're not getting the right barrel to fire after firing the left first, I would suggest you need to get it serviced by someone qualified.

That trigger, like more than one English single trigger, was not exactly a roaring success. It has been a long time since it was used, no doubt for good reason.
Someone "qualified" to work on it might be harder to find than a gun so equipped.
A wonderful candidate for conversion to double triggers, in my humble opinion.

Best,

Oh sorry I have not tried the trigger. A friend told me that Holland single triggers when pushed forward it only shot the left barrel and only the left barrel. I have not tried myself as I have only been looking at it.
So it may work fine.
Just asking if anyone has heard of problems with the Holland single trigger.

Main problems are -
1 age and wear
2 people who have no idea what they are doing working on them
3 having the gun restocked or being renovated and
having the metal work let further into the wood

I don't have any direct experience with H&H single triggers but H&H most certainly did make what was called a "semi selective trigger" which allowed the user to fire the left bbl only & not resetting to fire the right bbl.

In the Donald Dallas H&H book the patent for this trigger is listed as the "Henry Holland & Thomas Woodward Semi Selective Trigger" & initially had an external selector but I know that some H&H "semi selective triggers" used the method of pushing the trigger forward to select the left bbl.

FWIW the Dallas book lists 8 different single trigger patents that H&H held but does not discuss which were actually used in production.

The Holland Firm has been renown for many things over the years, including unfortunately the legacy of their multiple early Single Trigger attempts, none of which proved even a close competitor of the one provided by T. Boss & Co.
