Indianapolis in 1963 - good chance it came from National Billiards in Cincinnati - they sold
Katz cues. They would use exactly that combination of joint collars to make
"jointed cues" out of house cues with warped shafts.
The sharp point ends(bottoms) of the maple are correct for a Katz house cue.
If the pin is 5/16 - 12 I would bet my lunch money it is a 'Katz conversion" from National.
Should it be 5/16 -14, then likely a Brunswick - quite Possibly from A. E. Schmidt in
St Louis.
Either way, a classy old cue.
