Now completed full restoration of this machine which was a very satisfying experience. The important aspects were to correct improper operation of Grandma; repaint the painted sides and carry out various resto issues.
The Grandma skeleton was completely disassembled.

Reassembly and adjustment of the function turnbuckles x8 required some patience and perseverance. A repro rubber right hand was fitted.

A new power cord installed including grounding to the skeleton, dispensing unit and transformer. A friend in the aviation industry let me have a jar of 'avigel' which is tremendous for sealing joins/ties on wax lacing tape.

A lid per original specs was fabricated for the coin box.

The coin meter was inoperative and the lens appeared it had been hit with a soldering iron. Cleared grit between 3 and 4 and fabricated a new curved lens.

Repainted the cab sides - quite an easy stencil job!

Final pics. The machine is now operating correctly although I believe the 115v drive motor is struggling due to age and wear. I am exploring options to resolve.
