So because there is a different standard for bottom bracket threading to
British, British BB threading is no longer a standard?
If you want to use the Herse brakes, distance between posts should be:
62 - 84 mm. According to discussions I've seen on the forums, back in
the heyday of cantilever brakes on MTBs Shimano decreed that posts would
be 80mm apart. Evidently in the past (perhaps even distant past) that
spacing had been 60. The modern standard is 80mm, and it's said all the
brakes designed in the last 25 years are built for that.

Sorry Steve, no standard. A standard to be a standard must be
universal, independent of brands of parts, frame or builder. British
BB threading, that's a standard.

There is a standard, it's just that not everybody has followed
it. Most cantilever brakes try to incorporate a lot of
adjustability to compensate for that. Since the Herse brake is
primarily intended for custom bikes, the expectation is the
builder will adhere to the published specifications. In that
context, it's a reasonable expectation. Obviously that doesn't
work really well for retrofitting onto an existing frame made with
any old whimsical canti post spacing. However, it's not too
likely you'd be putting brakes that cost that much on such a frame
in the first place.
