Ciao Joe, welcome abroad.
U are in the right place to ask and learn everything about gt40s.
U also are lucky cause living in UK, and so surely u will found asap (when u get a driving license maybe)a nice gt to start live the dream.
From pictures u posted I think that car is a kva (for sale on ebay uk sometimes ago).U can recognize it from the strange suspension on the rear axle,from some parts of the chassis and from the generic quality of build (seems a car build some years ago..when less replicas were available)
I am anyway not 100% sure of it..surely many other guys here in the forum can give u a better answer.
Kva were some of the first replicas available on the market, many many years ago,today u can buy too better and excellent cars and find a lot of hlpful people ready to give u an hand during the building process.
Just ejoy some weeks gaming with search button asking everything u want..and u will found an answer.
I wellknow what blast is to see a gt40,and if u had the same strike to your heart...u can only go on loving it and maybe join one of the wonderful clubs u have in Uk (I did it..from italy
..joining the enthusiast club uk...too nice)
ciao 4 now
Paolo
