Just today. I'm planning to give an Olympia SM2 with a freshly resurfaced platen, new rubber bushings, a fresh ribbon, a non-slip mat, and a felt mat to a close friend as a gift. The young lady was so happy to try a typewriter that I couldn't resist. It's her birthday and Christmas gift for the last years. The cleaning of the slugs was the last bit I could do for that machine. I hope it will see a bright future.
