Tom. Nice to meet you although I am surprised we haven't come across each other before. I am working on the FV1620 getting it ready for the reunion of the Para Sqn RAC reunion. Here it is last year at Bovy Camp (not museum)
Then week after that got to finish the FV1609 which is back to bare metal on most of it.
But armoured stuff takes a lot of time to rust thats why yours are so rare. Which I supose is not just the thiness of metal itself but many will have been in breakdown role & out all weather in our salt laden roads.
I assume I will see the two FV1604s of Chris Pearce & John TC at Horndean. Although I am into Land Rovers they are no2. I suppose Humbers represent my childhood of the Dinky toy era & the toys are just a bit bigger now.
