I bought a Minox 35 EL sub-miniature camera at a swap meet. It is in excellent condition. Poul from Denmark kindly sold me two batteries for it (they cost almost as much as I paid for the camera). The Minox was in a leather full case with a matching wrist strap (in excellent condition). The original purchase receipt was in the case ($178 in 1977!). Batteries had been left in it, but they did no harm. As soon as I put a new battery in it, the meter jumped right on. I checked it against my hand-held and it is correct.
