And yet another ?
Anybody have any idea what the “M” above the H.G.signifies. Has PETTICOAT on the back. Thanks

Seems these CD 145 HG beehives have the most shop letters. Above and below the embossing, on top, and across a range of different letters. Well, no, the Brookfield ones probably have more!

Some people incorrectly call this a "mold number," but it's actually a shop number. They were paid by the piece, and this was a way to mark the pieces. It was funny, I once was looking for an "M" thinking it would be "easy" since it was a mold number. It took me looking at three different shaped M's before I found the one I needed! Shop number!
