BITZER!! But of what era?

[Sheffield_Tiger]

Yes I know it needs a clean

Yes, I know about the chainring bolt...it's an emergency and will be ridden gingerly tomorrow on inner ring only (well it doesn't have a front mech yet)

So what era is this from then? 70s Puch. 90s Biopace. Early 2000's STX shifters. Current Avid brake levers. It works, why not? :-)
