Yes, a 350 with 7,5:1 CR piston and a Franklin P2 cam (~HS MkI -54) It is originally a W/NG made in 1940, early one. As it was missing so much original W/NG parts, and already had been civilianized by former owners, I went for a -39 ISDT look-a-like. It will be used when ready, already yearning for spring and summer to go into the mountains with it. I am putting the horn on a homemade bracket, that will attach to the field stand pivot bolt on the frame. I am going to put twin exhausts on it, so no field stand. The frame cover plates and the horn bracket I do not have, neither an original Altette - but a 12V repro I bought at Stafford. Going with 12V on this one, with a new 12V/100w alternator made in Poland.
