Truly an incredible collection, It would be a full time job to keep up with just the dusting of all those machines,
Climate controlled no doubt. I could imagine if it wasn't, I could hear all those tanks rusting and tires dry rotting all the way back to my house.
The only way that I can see how to fund a coolection this size would be a not for profit museum,with membership and volunteer support....incredible, I would join if it were closer. Although I must say , a collection such as this requires a larger space for the machines so that there is enough space between each machine to be appreciated singularly.....and have drooling stations for guests every so often.
