I will post some more pix up later.
Rear derailleur is fine, it's had a 5 speed cassette put on so doesn't index properly, that along with a fooked cable and someone messing around with the grub screw stops.
It's similar spec to a courier but with shimano brake caliper on front and shimano version of an AD990 on rear. Geometry is slightly different to all others in the range and it rides really nice.
Just needs a strip down, clean and full service.
