CAMPAGNOLO date code de-coding

My Chorus crankset has a "41" stamp in side of square shape. Are these from 1991?
They will be put on an Italian bike with a Cinelli BB shell. Any idea of proper BB spindle length? 111mm?

I asked the same question re the 41 in a square. Was told by vpiuva it is 1988. Can't help you on the spindle length.

I know the BB I'm using with my "41" Chorus crankset (on the Bertoni) is not the modern 102mm, and I have a correct 43.5mm chainline (double). I wish there was a good way to measure it while assembled, but I think I ended up with a ~111mm spindle. I tried out several different BBs.
