Did IH use ID tags on prototypes?

Did they use any type of tag like what we're familiar with or some variant of it, or something different?

Pretty sure they did, but maybe not on everything. Saw an M once with a smaller tag with a Q- then a stamped number. There was also a pic once posted on here of an M or H with a similar tag on it.

Wish I could find a pic of on that may have been used on the SM/SMTA

Some did, picture of one on M engine. Gas power engine works with a Q prefix number. Sorry picture not clear.

Interesting. I found a sm with a really, really offbeat sn tag. I'll post some pics later.

Correction that said GAS POWER ENG. DEPT.
TRACTOR WORKS. May not be able to see it in the picture I posted but its interesting that the steering shaft appears to have a coupling near the radiator, Block casting number is near front instead of rear like most, throttle linkage is different and the rocker arms look like ones used on later tractors and not like early ones. If vent pipe openings are in the top side of head they are not visual. Can see the front opening.
