Correct Front Bumper Arms

[Dave Pratt - IL]

According to the Judging Standards, the front bumper arms changed from square ends to rounded ends in 1931. The square ones were used until mid-'31. The rounded ends could be used starting in early '31. What I don't understand is if this is referring to both ends or only one. Seaching through my stack of arms, I find 3 versions:
- Both ends square
- Both ends rounded
- One end rounded and one end square

What am I missing?

Okay. Can the end against the frame be either square or rounded on a late '31?

That is an interesting question as I don't recall ever seeing ANY front bumper arms with squared mounting ends regardless of year. I don't believe they would clear the front fender brackets at the frame except POSSIBLY late '29 and early '30 where the front fender brackets were narrow and mounted with two bolts each placed vertically. I'd sure like to see a pic of those odd bumper arms!
