R100 help to Identify

[Oggyr80]

Had an R100 engine for a year or 2 now, which I'm going to put up for sale, and need help identifying. 247/51 is printed on it as well as a 6 digit number and a 7 digit number. Which numbers do I need to identify it's model and age?

Looks like a 79/80. Is there a condensor on the side of the bean can?

I don't know TBH. I've asked a similar question myself before now. I'm sure there will be a matrix or something somewhere but I haven't come across it.

Where are the numbers ? On the lower left of the case, or around the oil filler/dipstick hole ?
