Help Identify Early(?) Linkage

[footclutch]

I have these 2 linkage parts in my Excelsior Henderson drawer. I don't think they belong, pretty sure.
The small hole at the top looks like it captures a cable, and the side hole is threaded on one side to clamp down and hold.
The large hole near the threaded nipple is straight through and measures about .310
The threaded nipple is 3/8".
Shown in pics are all 4 sides.
These are NOS and have a little nickel left on them.
Any thoughts?
Thanks, John in VA.

Hi John,
These screw into the crankcase on a 1915 and Series 16 Excelsior. They take the cable from the pedal for the gearbox interlock.
