Those posts are the first from that manufacturer I have seen. Some French b ikes from the 60's, maybe 50's, mainly heavy demi-course types had a back b rake mounting hole drilled vertically through the bridge, not horizontal as normal. The technical reason for this I can't remember, if there was one. Mostly you will find bikes with this mounting type equipped with Mafac Dura l, or more likely CLB, in both cases centerpull. Both Mafac and CLB had pro prietray back plates, sometimes an inegral part of the brake (some CLB). So , you are looking at a unusual item I'd guess, Weinmann weren't often fitte d as standard with that fixture. Nick March, Agen, 47000 Lot et Garonne, France
" Just saw these on ebay, and am guessing that they fit cantilever brake bosses or something, but I'm stumped:

I'm sure that someone out in CR land can enlighten us...
Thanks,
