I picked up a 1970 Midway Haunted House gun game at Coin-Op Warehouse in Maryland years ago. It was under a roof that collapsed from water. I found a replacement backglass and 8-Track tape then proceded to do wood work and a stencil job.
Cardboard, wax paper, and a razor to make the templates.
Here is the black template on the kitchen floor.
Template 1, purple
The back door hinges were ripping out.
When I opened it the door fell off.
I had to remove and mount all of the relays onto some fresh wood.
