Does this say No. 1 1/2?





Alloy artifacts has a #1 shown so do these come in half sizes like it seems to look?

I think I have a 1 1/2, I'll try to look tomorrow. I have larger alligators that have 1/2 on them.

I found one of those 1-1/2 size alligators a couple of weeks ago.

You can faintly see BULLDOG on the side marked No 1 1/2.
You wrench is the same as mine.

At some point in the early 20th Century,  1 1/2 as an alligator wrench size got connected to that single alligator wrench with multiple square nut sizes in the handle. 
A similar wrench appears in a 1902 KEYSTONE ad with size 1 1/2:
