Thanks Chris!
I don't have Yvert, but Scott doesn't say anything about the hair directly above the ear. To quote my 2015 Classic Specialized:
"Die I. The curl above the forehead directly below the "R" of "EMPIRE" is made up two lines very close together, often appearing to form a single thick line. There is no shading across the neck.
Die II. The curl is made of two distinct, more widely separated lines lines. There are lines of shading across the upper neck."
Here's a blow-up of the above image:

The arrows are pointing to the lower ends of the lines I think they are talking about, which would make it a Die I.
...but that little nick that might be the bottom of a perf hole is concerning!
So I agree with your overall assessment. (too many maybe's!) I'm slowly building Steiner albums and moving all my stuff that I've never been a serious collector of into those. I'm using good paper back-to-back inside document protectors and top-loading clear mounts. So "Ol'e Louie B." is in a loose mount inside the protector to rattle around until I find affordable replacement(s)!
Thanks for your help,
Al
