No, they generally mount via a center bolt, like most centerpulls. They may work a bit better when brazed-on, but they don't have to be mounted that way, and usually weren't, historically.
Picchio, thanks! I suspected as much but couldn't find any photos except front views which made it impossible to tell.
I have a neat little chrome TA bag support that was OE on the Peugeot. Now I know I can use it if I get some Mafac Competions (also OE for the Peugeot PX60). I guess it might even add a little stiffness to the calliper.
I wasn't aware that Mafac made them. I've only seen the T.A. version. There was a flood of them on eBay recently. I'm looking for the version that has a mount for a flashlight.
I think TA or one of the companies that distributed them must have just dumped a lot of old stock inventory because I keep seeing LOTS of NOS TA stuff showing up. I haven't seen the TA version, but I do see these MAFAC racks on eBay sometimes.
Hey Dawes-man: if you're buying a set of MAFAC Competitions, be certain that you get the straddle cables. They are specific to the brake, unlike the Racer brakes, and they are NLA. Personally I run Racers because they are cheap and you can use standard cables for the the straddle cable. The only real advantage to the Competitions is the bronze bushings vs plastic on the Racers, as far as I can tell. Racers are still indestructible, though. I took them apart and laid the arms on top of each other and the geometry is the same except for the shorter reach on the Competitions. Some day I might get a set of bronze bushings pressed into a set of Racer arms and have the "perfect" brake.
They're made to fit under MAFAC brakes. Perhaps that's what you're referring to. Or maybe not.
You may be right! The seller was in no doubt and referred to them as #270 in the TA catalogue. This one has what I thought was 'TA. MADE IN FRANCE' written on it but now you mention it, it looks like 'I.A. MADE IN FRANCE' It is the same as the one on Velo Orange, which is the same as the one in the thumbnail below. The bike is the same as mine, too

Thanks for the warning, Karl. Thanks to this forum I've got that covered. I need all the fitting parts so I'll probably go for NOS but there's something in the air and everyone is bidding so high for just about everything I want this month
