I just got a pair of pannier frames of which one has the 2 Norton 16H brackets(photo 1 )and the other one another type. Having never seen the brackets on photo 2 and 3 I was wondering if this is correct for 16H aswell. Or perhaps another model...or just home made?
The bracket in photo 1 on the right hand side of the pannier frame and the same one above in red paint look similar or are Triumph 3HW.
I'm not a specialist, but they look like Norton parts to me. Or did Norton and Triumph use the same brackets? (After all, they did use the same pannier frames...)
