Yes, that transport museum was brill. Being a Beverley lad, I used to go in there regularly and knew a lot of the people who worked there. I even got permission to take some of the fine sand from one of the displays - I think there was a half track in N. Africa livery there - for my own little diorama I was making at the time.
There was a massive display of 1/72 models there too - some bloke (you'll probably know him, you lot, though I can't remember his name - had donated or allowed them to display his collection of aircraft.
First time I went to Fort Paull was for a re-enactment and I was sorely disappointed with the way things were displayed. No chance it would ever have lasted long as the chance of repeat visitors was pretty nil without some independent event to attract them back.
Good car boot at Paull sportsfield though, first Saturday of the month April until October - weather and infection permitting!
