Looking for some help on this one. I've had it for a couple of years now-- Winston, you may remember me showing you this one.
Agree that it's trimmed so close, it would be impossible to call it an imperf Type IIIA or possible Type III, but hate the idea that someone could've trimmed some bad perfs to make it look like an imperf.
Here's the full image:
And a blown up top and bottom:


I'm sure it's a "B" relief, and has some similarities to a few positions, but not a dead match for any on Doporto's site.
Best possibility I can see could maybe be 20L4, with the marks in "OST". I can see the fainter mark in "O", and the gouge at the top of the "T". On some of Doporto's examples there is a gouge in the "S" and some not. Blurs above where the line would be could be supportive of this position also, maybe?
There's a faint scratch across the top of "E" in ONE that isn't listed anywhere, and I can only wish that there was an extra 2mm at the bottom!
Thoughts anyone? Thanks for your help. You guys are all the best!
