Spitfire parts in England

["Huw Upshall" <hupshall@wolfenet.com>]

I'm in England for a vacation right now and I was wondering, would It be
cheaper here than back in the states to find a twin SU manifold and carbs
for a 1500 spit?  If so, can someone tell me of some good local parts
suppliers or scrap yards that might have these parts?  I am currently in
South Wales, I will also be down in the Salisbury area and London during my
stay.
