ISTR Monarch was one of the house brands for a dept. store like Montgomery Wards or similar??
I wouldn't put a lot of money into that one. It has the 3 arm "cottered" cranks from the late 60's or so.

The trike looks like a Shimano 3 speed. Something like 333 or SCS. I think they are the same, but people read them differently because of the "font" used. They are not known for being very strong.
