Got this in a lot of fenders for Ts and As.
It looks similar to an early accessory front end brace or radius rod brace type thing? Each arm is about 2-3 feet long and can rotate within the triangular hinge.
Yes, front r.r. accessory - additional support for over the top radius rods.
Awesome, thanks Steve!
Off to the classifieds it goes. No use for it.
