[Techlunch] Micro Drive Belts

[techlunch at happy.emu.id.au]

G'day All,
Yes, I know its been a while, but I am still above ground.

I am trying to identify a micro-toothed belt used in an
auto antenna tuner.  This has double edged teeth off a
central spine and drives double sprockets separated by
about 3mm.  The tooth pitch is about 2.5mm.

I have seen this drive type before but I am at a loss as
to what to call it and hence search.

Anyone know what I am talking about?

Thanks,
DG
