Liberator Mk1 ?
With the B-25, I had no idea what I was looking at, and I made the mistake of letting the colours deceive me. When it was stated it was a twin, I thought maybe the Navy version of the B-25, but then forgot it when Aaron said it wasn't Navy!
Hmm. Methinks perhaps an Italian type? But no idea what, without going to my library - which is currently in four, tall, and heavy piles, awaiting construction of the new bookshelves !
