Richard Ebeling writes: I have a blue metal Erector set box, 18″ x 10″ x 3″, and a 1939 manual. The boxed set appears to have been supplemented with additional sets or project instructions, one dated 1969. The box is filled to the top (very heavy). I would Like to put this in the hands of a group or collector. Perhaps the pieces could supplement or replace items of other sets. I live in Aurora, Illinois. Richard Ebeling (maebeling@att.net).
