Genuine and original pieces of WW2 aviation history are becoming rarer and hard to find and once my stock is depleted there will be no more.
I do still have some Boost gauges still in wax sealed boxes which at the end of WW2 were destined for the far east but never sent. These boxes remain sealed just as they were 75 years ago and it will either be marked with the WD arrow or the Kings Crown but I cannot say which.
This might be the last new original stock boost gauge with the Crown & AM so why bother to pay as much for a replica gauge when you can have an original part from the RAF stores?
Just like the Spitfire these will only increase in value as time passes.
