How long did Lancaster Arms Co. and Alfred Harvey Worrest install his Infallible Single Trigger. We know Ithaca used them before The Great War --



but here is one popped up on GI on a 1926 vintage NID --

Have had several on Bakers from 1905-1915, but that does not say when they were installed.

The Lancaster County Historical Society reports Lancaster Arms Co. operated at 126 E. King St. from 1910 until about 1918

I have a very late Lefever Arms Company H grade with a very high serial number (over 73K) which is fitted with an Infallible trigger. I can't prove it but highly suspect it was installed at Ithaca when the gun was built. Can't say for positive if it was before or after The Great War, but also suspect it was one of the near-final guns to leave Ithaca. Frame & barrel have different SNs 4-digits apart. It has the 1907 patent date & while it has H style engraving, Doll's Head & Cocking indicators it has DS wood. Un-capped half pistol grip & no Escutcheon nor metal tip in the forend.

2-piper, that's interesting - I also have a late H grade Lefever assembled by Ithaca with an Infallible trigger. The serial number is 71xxx. As you know, it is difficult to put an exact date on the sideplate Lefevers, but it could have been made as late as 1919. Like you, I can't be sure the trigger was on the gun when it left the factory, but I suspect that to be the case.

The forend serial number on my gun doesn't match the frame and barrel and appears to be for a DS model.

Interesting Jack; My gun has SN 73,338 on the frame & 73,342 on the barrels. This one has 28" twist barrels & weighs in @ 6½ lbs. The last account I had these were the highest numbers yet recorded on a side plated Lefever. Both chokes are identical at about a ¼ choke.
