Okay...

I see it now.
Let's take an inventory... It has an Amazing Maze... Hey! You owned one of those!
It has a Turbo... Hm... I think you owned one of those, too.
A Millipede... Hey! Didn't you JUST clean up a Millipede cab? That one looks like it had just been stripped. Incredible.
And there is a Stargate that I initially thought had a Street Fighter setup... But no American SF conversion I have ever seen has used the balltop joys. It must be in the process of being MAMEd! PLUS, it has the overlay that was offered on this very forums buy/sell/trade forum. Uncanny! Whoever owns that warehouse put brand spanking new joys and buttons on that Stargate cab.
Is that a Battlezone I see? Hm... I don't think you ever mentioned ever owning one of those... OH! WAIT! Yes you did.
And a... Gorf. Hm... If I pick the furthest reaches of my brain, I seem to recall you mentioning you had one of those, too.
All that's missing is the Time Pilot cocktail, and I'd say that this warehouse is the smack-twin of your project collection! You should get together with the owner of that warehouse so you and the owner of those cabs can get together and swap parts.
