This is a rare Keystone speedboat model #214. It measures 18″ x 3.5″. The wind up motor is detachable when slid on its clip. The boat is from 1934, the year that Keystone fully incorporated Jacrim Mfg. into the company. This is reflected in the logo that states Jacrim boat mfg. by Keystone. Being that the motors came off so easily they are often missing. I have seen only two of these for sale, this one and another without the motor.
From my private collection.
Very nice I wish I had it in my collection
