hi eric
if that truck came from new castle, then it very likely served with the North Shore N.B. Regiment. if i were you i would be hitting the legion with some photo's of your truck and asking some of the lads if they remember it...who knows, maybe one of them has pictures of it, or possibly used it then. having the history of your vehicle first hand makes it even more special. mon grandpere et deux oncles travaille don le Regt Nord Shore Nouveau brunswick 1939- 1946. pardon my french, it's not that great.
