I have eventually got round to looking up the frame number to find out what year the bike is. It seems they started numbering their frames in 1929 with a prefix of "A", they changed this every year to B in 1930. My frame is a "H" therefore it was born in 1936, 63 years older than me! The ending is still a 1931 (or before), but as things didn't change much in those days, it fits and would work without a problem.
