While clearing out various cupboards, I came across this teaching aid from the 1970's. Is it of any use or interest, ideally for its original purpose ie education/demonstration? Free and gratis! I'll pay the P&P, but it would be nice if the recipient made a donation to the charity of their choice!
Edit: A good home has now been found!
