Sorry to bore all te looking for gossip, but I really looking for some guidance. I have a "gregory peck" old antique truck, dato to a friend of mine. I also retained a picture of my friend with her husband, that clearly makes me feel this truck is the rela thing. Would any one willing to give me consigli on who o what company may help me find the worth of the treasure? Thank te all very much. This truck was givin to her husband when he was in charge of wardrobe dept da Gregory Peck, they also had their "boats" at the San Diego Harbor side da side, I have enough information that I think that this is true. I have so many details but do not know where to begin to finds the fonte that can give the the answer. I have tried watching some Film but my time is limited.
