Best padlock 1b series dimensions?

[hatrabbit]

I was told an old Best padlock of mine is possibly a '1b series' lock. I can't find any info on this series, can someone here tell me whether my lock is indeed a 1b? If I can properly post this pic it'll show the approximate dimensions of the body of padlock I have...

Why not post a picture of your actual lock?

If it has a REALLY thin shackle it is an 1B. If it is a bit thicker it is a 2B.

2B or not 2B. That is the question.
