The only deficient stamp I've run into was on a Greek-made Amadeus, where the stamp just says deus.
It's good Greek briar pot and about fifty bucks, so I went with it, but I was disappointed. All of my
Petersons, from various years and sizes and shapes, have worked out fine, so I am a Peterson fan, but
I understand the disappointment when things aren't just right, whatever a pipe costs. In your place,
I'd smoke it and enjoy it -- I'm a smoker, not a collector, so as long as I know where it's from, I'm not
hugely concerned.
