The Rolex Submariner (vintage)

[Paul Allen's Rolex]

Apologies if this thread is slightly too old to bump, but I was searching for relevant posts, and wanted to ask those of you with much more experience.

I'm not particularly experienced with Submariners, but I've been offered this particular example in a country I'm visiting next month. I'm slightly dubious of the very fair price and the fact that I've seen some 'superclone' versions online, made to look aged. I've said I will take it to get authenticated prior to parting with cash, but I know some of you here will be able to immediately identify any little inconsistencies.

These are the photos I have so far until I visit in person:
