Wow great machine collection you have there,all the best with the sale and hope you still around pinside as i enjoy and seem onside with alot of your posts.
I know what its like to get a little burnt out with collecting hobbies...i had a large collection of vintage generation 1 Transformers boxed etc which i had been collecting for approx 5 years and even though the time came when i was over it i still felt sick seeing them up there for sale and yet once sold ,money in hand, i actually found i didn't miss them.
