Grandfather's c1923 Model 18 Norton

Sent by Al in the UK.

"This shot is of my grandfather (who was a great Norton fan who used to visit Brookland regularly pre war) and my grandmother on his Model 18 at Hayling Island, Hampshire sometime in the late 1920's. I wonder if PC 3978 is still around. (JdK: PC 3978 was issued from July 1921 to July 1923 by Surrey C.C. (currently Guildford). It probably is a 1923 model then. Quite sporty, note the narrow mudguards, open primary chaincase and open exhaust). I've been trying to get hold of a flat tank Model 18 for ages similar to his! I'm looking for a flat tank Model 18 - project / box of bits, or what have you ? I have a 1923 Sunbeam 500 sv Sports TT short stroke flat tanker, 100% original for possible exchange; the bike is MOT's and taxed with a rebuilt engine. (below)"

1923 Model 18 cylinder head - For sale

Chance to buy a rare very early OHV Norton cylinder head dating from October 1923 (stamped 23/10).  This head has had valve seat inserts fitted at some stage in its long life, and has regrettably sufferd a fair amount of fin damage which will need to be repaired, but the head (including the threads on both inlet and exhaust ports) is basically in sound condition. On Ebay motors, item 260773524448. See this blog entry for the difference between early- and later M18 heads.
