That's really a great help, Chaps. I might have time to go and see it today and I'll take some pictures of the engine numbers, I didn't think that LAK/188/56 could be right, I wonder if 56 could be referring to the year. I know the machine has been in the same family for donkeys years. Jan do you have any idea from the key cards where it went after it left the factory?
Thanks once again for your help.

Sold in Ruddington on 15/09/1960. Please contact Lex if you want a hi-res scan of the KeyCard with your number. It is part of the history of this bike.
Typical!! Any news on 20399 in the key cards Jan? Ron
Unfortunately I can't find your number in the KeyCards Ron. Number 20402 is in the list, this one had census number C4589077. But as explained, the numbers can't be calculated, so your number C4589174 will be very close.
