As you can see a few bits are missing, the engine and frame numbers match GC 186--B25S and from various sources suggest it is from late 1969. The engine turns over nicely, and will probably run, but would be best to strip and clean and go through it, lots of useful parts still on it.
Please call us if you are interested in anything from this bike.
Please note some of the parts may have already been sold. If you are interested or require any further information, please call us on (01978) 266087. Thank you.
