I have a TL-Electro of about the same vintage. Bought it used at a pawn shop in 1983 or so. Tried selling it, giving it away, but it always comes back home. Decided to take advantage of the current trend back towards analogue processes and am pleased to report that, after installing a new battery, it works as well as ever! Why, oh why, did I give it up for a Leica? :)
