HELP- identify this mystery trademark please?

I don’t know this one and a member has asked what company it is- it’s not in Joanne/Joan’s brilliant book ‘Charms and Charm Bracelets’ by Schiffer or any of the charm mark websites I can find- and I’ve had no luck with the patent marks. The closest I can see is the Bell Tradeing Post of Albuquerque New Mexico but it seems more detailed than that one. Does anyone out there know? Please be a hero and identify.
