Got this yesterday from an eBay seller and was dismayed to find that the keys were frozen. I tried to fix that with denatured alcohol, but nothing moved. I contacted TypeWriterKing, who has much more experience than I do in these matters, and he suggested lubing all moving parts with hot tranny fluid. I did so, being sure to coat all moving parts and spritzing penetrating oilf for good measure. After a mere half hour, all keys were freed and I was typing. I was stunned by the efficiency of this method, and will use it from now on instead of denatured alcohol, which mars painted surfaces.
