Miller dynamo number/date codes

[Keith Martin]

On Lucas Dynamos there are dates stamped on housings. Do these numbers on Millers dynamos show date of manufacture? Is 58 the year of this dynamo?

Hi!

I don't think so. Otherwise my D6 dynamo would be from 1973.

Looks like a 'mating' number like crankcase.
