Here was my vacation project: A rusty, corroded and maybe slightly overpriced ($17) mess from an antique shop (a 1962 Slim), that nevertheless appeared to be fully functional. I forgot to take before pictures, but it wasn't pretty: huge gobs of brown rust from an ancient blade that was still inside, pitted, bare brass patches, some of which had turned green. Alternate baths in white vinegar and hot water and dawn got it this far. Some Maas polish returned the shine to parts that weren't too far gone. I've had four excellent shaves with it. The blade loads and aligns perfectly, the doors close and lock smoothly, it clicks through all 9 settings perfectly, and the only apparent flaw is that one of the safety bars appears slightly bent, with no impact on the shave as far as I can tell. Should I cash in my chips here?
