Hi Mal, just as a comparison my Model 5 has the 2 side skirt holes, edger slot and cover (with spring clip attachment) base and height adjuster extensions and Engine No AA 14992 and single digit '6' on the lower crankcase.
Could you give me please the approximate year of manufacture? Also am I correct in assuming that it is an early Model 5 Special?
Thanks mate,
cheers2
