Is that a cast iron base? Looks like an alloy one to me - I don't think the locating pin for the headstock was used on cast iron. As regards paint, the problem many of us have is that we are so used to seeing the hammered green it is hard to imagine anything else, but the early ones were black. I think a high gloss finish white like on the U3 would be good for someone who makes a point of keeping it clean. There are some very hard paints available for home use these days. I don't recognise that motor, but if there are time limits it should say so on the rating plate.
