Can anyone tell me when Marstons introduced the model number onto the brass disc fixed to the timing cover?
well, I have 3 bikes from 1932, the model 90, model 9 and lion, they all have the model on the brass disc, my 31 model 9 does not, non of my earlier bikes have it either so i'd guess its 32
I'd also have an educated guess at 1932 season as well.
My 1931 Model 10 doesn't have the model number. But then who knows whether the cover started life with the bike?
Andy, nice to see an example of somebody researching this forum which contains a wealth of information...... forgotton I posted my input a f ew years back.
Might make a mention of this subject in my Beaming southern notes.
