No worries Jeremy there is a bit of a craze to label everything PBP these days when its just a standard tri logo variant. Everyone does it though. I don't think even the COO experts agree.
My personal thoughts are that if there are no significantly unique distinctions that can be agreed on then collectors are clutching at straws to label it a unique PBP variant. There were so many moulds used during each figures production with very slight differences or small marks here and there - it would be almost impossible to match such a small difference up to a specific manufacturer.
At least that my opinion - I'm sure plenty will disagree

Rest assured i'm sure you can get away with calling it anything you like, but if your going to call it PBP then do yourself a favour and put the price up - there seems to be a premium on them at the moment.
Yes I've seen Wolff's chart. He is the COO expert, but it was done a while ago.
