The numbers indicate they years after 1980. '5' would mean 1985.
23 would mean 2003, according to Pipephil.
But he's not going into details.
From the few examples I've seen, Craig now uses triple
digits, ex. '222' meaning 2022; '223' meaning 2023.

the briar but, rather, on the silver band.
Technically, yes, you would probably be right in your assumption
this is an 1985 or 1986 pipe.
