Hi
I'd check with palces like Motion Industries, here in the states.
I've used some ladder belt drive pullies in the past for projects.
You might find that it is a standard pitch, available from one of
their suppliers.
They may have changed there name but when I was getting
such things that was their name. They carried stuff by Boston
Gears as well.

The drive belt fro an HP9871 (daiswheel printer,
the belt is about 2m
long and looks like a ladder. I am told none have survived. This is one
printer I would love to find, just to see if I can work out some alternative)
I'm guessing that the rungs of the ladder go between teeth on the
pulleys, and the rails of the ladder keep the belt in place? In which
case, I'd get the closest matching toothed belt I could find and fit
little metal end cheeks on the pulleys to stop it sliding sideways. If
you were tight for space, you could probably get away with only one
pulley.
