It's Moore - Handley, with an "N". They were a Birmingham, Ala wholesale hardware jobbing firm. They sold their last folding knives in 1965.
Another Birmingham firm was Wimberly - Thomas.
Both sold pocketknives with their name on them, but any from Wimberly - Thomas are extremely rare. I've only seen two.
Several years ago, at a knife show in Dalton, GA, I purchased three mint, etched, celluloid handled Moore -Handley knives for three hundred dollars.
I brought them home, showed them to a local collector/dealer the next day and sold them for four-fifty.
Moore - Handley reorganized many years ago and I think they are still in business as HomeCrafters, Inc, although I don't know how they've fared since the coming of Home Depot and Lowes.
They were located on Highway 31 South between Birmingham and Pelham.
