I've had this antique Match Safe for many years. Only found out recently what it was. Found a similar one on an auction site that was (helpfully) engraved with the year 1848. It had the same makers mark on the bottom: PJP.
I found PJP mentioned twice in your forums and although some people apparently had some success discovering what PJP stood for, they didn't bother to share what they'd learned, which was disappointing.
PJP might be Swedish, German or Polish because one of the posts in this forum mentioned an old snuff box that was marked PJP and 12L (12 Loth.) One post thought it was Birmingham. Thank you for any assistance.
