Yep, I worked full-time as a volunteer about a year or so ago. Was having a career break from work so worked there for a few months. Say hi to John Delany, he is the collections guy and also Alicia Gurney. They didn't have the STUG III when I was there though. Managed to get the keys and get into lots of the vehicles in the Landwarfare Hall (Hetzer, T-55, SU100 etc)_ Ask John for the keys. I installed the Gun sight Optics in the Hetzer (when you get into it you will see that I put a chain and padlock around it!)I only worked that hall and wrote some captions. Enjoy yourself they are a great bunch!
