I also saw that SPC doesn't list year of manufacture for their estates; it'd be nice if they did.
For the same reason and because they recognise it's lead to them being the one of if not the most collected pipe brands.Really only pipes with silver adornment or dunhills can be dated. Dunhill started doing it for warranty, but now who knows why they still do it.
