Trying to come to a number

Well Mike as stated in my original thread I already found these pieces via another f a b o member and just wanted to strike up a conversation with other members as to what these pieces May cost or be worth I don't know what I was thinking
What is the seller asking or did he dump it back in your lap with a "wadda' ya' gimmme?. If so offer him $20 and deal from there. Have to start somewhere.
