Thanks for the info everyone. I am just curious how the truck could be the 28379 th off or the assembly line? Weren't there significantly less Cameo's produced in 1955 than that? (I thought there were less than 1500 produced). This truck does not have the engine or at least not the block....it does have a box of pistons/cylinder head/crank but I will check my photos to see if I managed to get casting numbers for them and post if found. Have a great day!
