I'd be intersted to see pictures of your MB. I've been working on this one for a few years now amongst other things. The engine has been at the rebuilders for a while so will hopefully have it back soon then it should be able to move again under it's own power. This one is a Willys script body, early-pressed grill MB, early April 1942.
I have only just started on the MBT, the frame and axle are in the background of the MB picture, just sourcing parts for it now.
I also have a GPW, this one is a Ford script body, early June 1942, ARN 159950 and is recorded as being allocated to the Long Range Weapons Project at Woomera.
I'm happy to help with your jeep parts storage problem if I can... I don't need too much for the MB but chasing a couple of front MB springs for the MBT if you have any spares?
