After seeing all these additional pictures, here's my theory. Someone(like myself) years back made up some fenders to combat the hard-to-get-on Loboy and sold them. It's even possible dealers had access to these fenders somehow, but internet wasn't here yet. I really don't think the IH factory made these because of the mix/match of metal work that was done. IH would have just continued their fancy half rolled edge all the way down. These two suspect fenders almost appear to have either round tube or solid roundstock as an edge and then metalfinished to blend. I could make these fender mods easy, several others on this site could too, like tst..
I still believe the manual pics are of a regular fender, just pencil drawn/viewed bad. A good sketch artist that could pencil draw these two suspect fenders would reveal a more true accurate picture. My feelings, it would look very different.
Mods,Is there any way to transfer/copy all these discussions/pictures over to the main forum so it's not lost a couple weeks down the road when the add runs out, If we all agree to it ??????
Just remember, all this talk is to reveal the truth so we all are comfortable with the results. We may never know the truth or maybe some new information will pop up to confirm things. Digging for the answers is good, long as we don't get our shorts all wadded up in a knot in the process
