I have my Dad's '60 'Fatboy' (left) in it's original packaging... it's well used... but I also have my Grandfather's '63 SuperSpeed that he used for 9 blades out of the original paper 10 blade package before his passing in late '63. The 10th blade, rusted, is still in the box. The razor and it's original plastic case are like new and I use it once a month (right).
Even his new razor can't hold a candle to the shave I get with his well worn Larkin straight (bottom). I shaved with it 4 hours ago.

I hope you find your 'birthday' razor... but I believe I've got you.
:D
