Anybody recognize this logo?

Messy , and complicated, some forge mark from an iron foundry in Indiana, contracted to Majestic co, which was a contrace hardware supplier for Mesker Bros....(Mesker Bros iron works, but they bought and sold more than they actually made)

("Brownie clamp co" was actually a paper division of Majestic co, Huntington,IA)

You're right that's a brain teaser. Where did you find your info?
I know how to make brownies now since I googled it.

OK, but do you know what to put in the brownies?
