I just had to update my Paypal account with proof of my name, address, and SSN to remove some restrictions they'd put on it. Something to do with IRS regs. I had to upload pics of my driver's license and SS card.
Any chance that 45 could be a length measurement and not a date? I ask only because I've had a couple other BB items with these labels and there was no date. My WWII officer's coat, for example, just has the chest size (41) and the sleeve lengths.
