Not the machine necessarily but vehicles with at least a cabinet or two getting transported from one location to another, often arcades. This Missile Command cabinet was in pretty good shape from what I could tell. I didn’t have any luck running into the owner. I would’ve asked if theirs had the special modification card which made the game harder. When it this video game first came out in 1981 at my local Aladdin’s Castle, I found it pretty difficult already but thanks to a Netflix documentary discussing the history of video games, I learned about some college students who turned their side business into careers with Atari.
