Again, ... seeking info and education. This much-worked-over high-wall trigger has a single, blued, slotted-head adjustment screw. It does not appear original. Is any information (or even speculation) available regarding who might have done such work? or when? Could this have been a mail-order item 100 years, or so ago? Thanks much, as ever. PS. Hope I got the attachments 'attached'

Or could be an over-travel adjustment screw modification. Cock the hammer on an empty chamber and turn the screw in; if it fires it is a set screw and if it does not fire and trigger will no move any further it’s an over-travel screw. Good luck.

best to pull the lower tang and show us some pictures on this ken

I just happened to have a non-set trigger high wall with a trigger that has the standard set trigger screw hole.  I inserted a 1/2" long screw and turned it all the way in.  It made no difference in trigger travel or other functions

2nd the opinion that looks like the right location for a single set trigger screw with an extra extra long replacement screw

the spring looks high compared to factory original  and the flats on the trigger appear below the tang more than average to me

swapping tangs and parts was often done and no reason the gun can't still have the wonderful trigger feel 1885s are know for

pics of tang removed from gun and different angle would shed more light on the situation

Another thanks, especially for the pictures, Rob. They are good enugh to show that mine is adjustable, but most likely not a set trigger as there is no screw on the front of the trigger. Happy Holidays to all.... Rob (too).

Is this what you are looking for Ken?  Been too long for me to remember the details!

There is only 1 screw for the single-set trigger.  Here are the parts from the MVA site.

Thanks yet again Bob, Ken, Jack.
These are really good phtotos (and the parts diagram, too -- and prettier than my rifle). And also, my photos could have been misleading because the other parts -- all there, and all working -- are disassembled & sitting in the customary Tupperware container. The deal is that I did not know what kind of trigger it was. I did try to make it "set' by pushing forward -- maybe too gently, and without turning the adjustment screw. All of this info will definitely sort things out once all the pieces are re-assembled. Thanks again & Happy 2024 to all.

Thanks. Sounds just like the slave-pin needed to reassemble the sear-disconnector setup on Colt Cold Cup 1911's. Meanwhile, .... still working on growing that 3rd arm .....

More High-Wall trigger-related questions: The attachments are photos of the Trigger Return Spring. I have looked at others in order to obtain a spare -- and have not seen any that have this lengthwise (? strain relief?) slit that appears to be original. Did it really leave the factory like that? And second, there's the Jan 29, 1901 Patent Date -- that I have not seen on others listed for sale, either. As ever, any info is greatly appreciated (and best New Year 2024 to all). Thanks.
