Offering for sale this restored 1940s shock machine made by Advance.
Machine has a reproduction top sign - otherwise is complete and original.
Excellent working condition - machine gives a very strong shock.
Original patent data still stenciled onto outside of base.
All metal case. Located in greater Los Angeles - shipping is available.
I have a YouTube video of the machine in operation.
Please send a PM if you're interested - I can send more photos and a link to see it in action.
