Nikon F-301

It is functionally very similar to the Nikon F-501 (sold in North America as the N2020), but without autofocus.

[2] The motor advances the film at a rate of 2.5 frames a second in continuous exposure mode.

This camera is powered by four AAA batteries, loaded from below, necessitating removal of the baseplate.

The placement of the batteries means that the tripod bush on the baseplate is extremely offset from the centre of the camera.
