I inherited a lovely old Clausing 5914 lathe with a ton of tooling. I've been working at getting it spruced up and thought about some touchup paint. It was painted by the previous owner with (KEM?) Lustral Machine Grey paint, which seems to be still available through Sherwin Williams but it's not really a consumer product and they don't list Machine Grey as an available color. There is a Grey 49 listed, but I only need a small amount. I'd like to stick with the paint that was used originally, but may not be able to find it nowadays. I expect the tool was refinished 40 years ago or longer. Anybody know where these paints can be had in sample sizes?
