Camcraft N-5 MP Motorwinder

very rare electric motor winder, made by Camcraft of Madison Wisconsin, speeds to 3.6 frames per second at speeds from 1/50th to 1/1000th. Craftcraft offered to modify the M2, M1, or MP for use with this device.  It has a large, separate battery pack, connected by coil, similar to the separate battery pack originally used on the Nikon F. A MOOLY like lever on the front on the camera connected the shutter release to the motor underneath the camera which was attached  to a somewhat awkward vertical style handgrip, in fine condition with original case, power supply with cable.
