October of '95 -- but what size?

In the last set of numbers, bottom right, the second character might be a 'B' such that it would read 5B01156

The bike is an R400 2.8 series and it looks to my eye to be a 56cm. I don't think it's a 58 cm . . . ?

(BTW, the bike in my avatar/profile is a Black Lightning. Not the bike I'm asking about)

Not sure if you can decipher frame size from the code. A 58 cm 2.8 measures about 57 cm from center of BB to top of top tube. I am sure, just measured one that has a size sticker on it.
