I have a few of these>never used & have the boxes. Bought them in the late '70's. What might they be worth?:thanks:

depends on model and color

mine is white cuz they didn,t make YELLOW

I stumbled across quite a few of those (the big ones) at an estate sale a few years back. If they are in mint condition, they are worth some good coin. I know of one antique collector who is a member of MSBA. He has all the books, and gave me the value of them.
