That's right Rick, well spotted. Never seen another 25 pdr with vacuum brakes. Good sensible addition for a carriage that simply MUST NOT FAIL during service. I bet it got meticulous overhauling in addition to the upgrade.
Mrs B got to sit in a Jeep while we were at the museum. I don't recall seeing this 'interactive exhibit' vehicle when I visited in September 2015, but it was a hurried visit that day.
And this is what will happen to me if any more military vehicles find their way to our place.
That said, I have been given a 1941 Ford CMP which is yet to be retrieved. That hasn't been discussed as yet.
Did you get my PM about your wheels?
