Exterior: It's a single action narrow spool, one piece foot/cage casting of aluminum. It has a polished line guide that appears to have been pressed in between the cage casting. The spool features a marbled winding knob with a polished chrome support cup beneath. Spool is also cast machined aluminum, approximately 3" in diameter, 13/16" wide, 2-3/4" diameter, held in place with a single slotted screw. Interior: The center post is brass, appears to be pressed into the aluminum housing. At six o' clock is what appears to be a zinc disc attached to the back of the cage by unknown means. The "drag" mechanism is unique (IMO), consisting of a curved flat brass arm riveted to the rear of the cage, and ending in a rounded cylindrical pad that rubs against the rear surface of the spool to prevent over-run. It is attached with 2 tiny rivets. There is a single logo raised into the rear inside casting of the cage, that will be the major clue to manufacturer's identity. See attached photos for detail of above described features. That's about all I can offer, other than the reel came from the estate of a man who began flyfishing as a poor lad on Long Island N.Y. in the 20's.
