Does anyone know what type of "string" Lionel used for the boom hook on the 6828 P&H crane truck? I'm assuming it's some type of nylon, thicker than sewing thread but thinner than the average yarn sting. Maybe kite string is closest equivalent?
I've got an original that doesn't have the original string, temporariliy using a thinner yarn for it in the meantime until I can find an original or reproduction that looks like the original; I don't think they used black string on the originals, some kind of silver-sh color, am I correct?
