My dad and I bought an unknown pre-war tandem frameset before lockdown in tasteful dog-poo brown and are finally getting round to doing something with it. I've been lost in a world of lugs and whatnot trying to see if we can find out what it is, but none of the usual mainstream suspects (BSA, Hercules, Sun, etc.) seemed to offer anything which has everything this does, so we've decided it was a custom one-off and are no longer bothered about what it is.
However, it has some interesting brazings on both the front and rear fork legs, which look like they might be something to do with brakes but I'm not sure what. I've had a delve into the world of non-mainstream pre-war brake oddities but have now admitted I'm out of my depth. The curiosity remains though, so... does anyone know what these might be for?
They're both the same distance above the rims. I found some French brakes which used similar brazings but at a 90 degree angle to how these are positioned (can't remember the name of them now), but frame has English bb threads and English sized wheels (26 x 1 3/8 ).
Any help welcomed, it's unlikely we'll use them as we're going for drum brakes but I'm itching to know what they're for!
