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.

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.
