IBM Model F 5155

I recently managed to find a post in which someone had found an old IBM 5155 portable terminal system that had been left to the elements. Naturally, the keyboard is completely corroded and none of the keys work as they are all seized up. Since Model F springs are pretty expensive, I will probably reuse the hammers and then put my spare Model M springs on it, which I've heard is actually quite similar to the original springs. I will also need to take a thorough cleaning to the keycaps, can hopefully get these polished up and back to good quality. I think the keyboard will be good to go once it's refurbished, but we'll have to see once I get the springs fixed. Pictured below is the 5155 system. It was found by /u/alumbrado.
