Those early numbers don't mean anything to me. Do you know what any of them 
mean? I suspect that each letter actually means something, but I've never known 
what. I've got some old (1970) service literature that mentions this 
designation for a lot of Bosch distributors, but there's no explanation given.

Just from looking at the parts, I'm guessing that the R stands for "Right", as 
in right hand rotation. They seem to do the same thing for generators, too, 
where I see both R & L.

In general, Bosch gave the complete distributor assembly a number, so that if 
any small thing on it changed, it got a whole new number.
