The Carom King, Hi Run, Keen Shot and the Medalist Pro are all hard to find in good shape.
Those cues were made only for a few years around the late 30's.
The wood on the Carom King looks amazing. The Keen Shot and the High Run are closely related, both were butterfly joints, High Run had two veneers and Keen Shot had none.
The Carom King evolved into the Titlist if I remember correctly.
In my opinion it is a deal.
The Garden City cue on the far right is no doubt the rarest of all of them, all though probably not the most valuable.
