How many 500's vs 550's

[Rozabikes Tim]

Random question but how many 500's were made in comparison to 550's. Don't know why but always felt 550's were the lesser of the two.... I spose the "how many originally imported to the UK" would be a follow on question too?

In UK a lot less 550 than 500 but US probably more 550 asthey got them from 74
