During repairs, I kept this machine as original as possible. No LED's. It's kept on coin play and all the coin chutes/validators work.
I prefer local pickup near Braselton Ga 30548 (50 miles N of Atlanta) but I won't mind breaking it down and meeting someone locally within 20 or so miles. I don't mind shipping but the buyer will need to make the arrangements.

I have a Williams 1976 Space Mission for sale.
Here is a thread I started when I first got it:

I judge the backglass to be a 7 (10 being perfect). It looses 3 points because I did extensive touch-up along the bottom around the ball in play lites (Looks good, see the discussion thread for details)... and slightly discolored white frosty paint around a couple score windows due to the usual effects of dirt on hot bulbs. Some of the original backglass paint (illuminated spacecraft etc) hasn't cracked but has "crystalized" making a very thin looking appearance but no visible cracks, no bare bulb filaments seen etc. It's overall appearance is good for the "General anyone".
The glass is sealed in Tripplethick.

There is a video on my youtube page:

The head and cab front had looked particularly dirty (As seen in the thread) so I repainted and re-applied the same graphic styles. Cab side paint is still original. The PF was touched up and sealed in Varathane. The Varathane finish wasn't sanded very much and still has somewhat orange peel surface. I kept it that way as I believe it helps preserve the original playing experience versus a glass smooth surface.
The cash box has a lid but no internal coin trays.
It has some paperwork included. I have copies on the rest of the info which I can burn onto a regular CD (PDF and picture files) keep with the game.

It was a complete game refurbishment.
*All metal parts cleaned/polished.
*Coils, switches, harnesses etc cleaned.
*All new sleeves
*Burned out score reel completely repaired
*New rubbers
*Many more

I've had very little problems with it since the rebuild posted on that thread.
I've given it yearly general maintenance (Cleaning, proper parts lube etc).
It's clean, it works 100% Set it up and play.
