Thanks! I didnt know where to start looking it looks like its the NEW hardbox set because there is nothing on the "top" half of my cap. https://www.mr-razor.com/Rasierer/The NEW/1930s NEW Hardbox Set.jpg
Start with a good soak in hot (nearly boiling) water and dish soap. Once that has cooled off, give it a quick scrub with an old toothbrush, then do it again. A couple of rounds should be enough to make it feel usable. If you need more than that, Scrubbing Bubbles can help, but you have to be careful not to strip the gold wash (unless you don't care about it).I’d liked to, what’s the best way of making it shine again?
+1! Great advice! I would be tempted to leave the patina on that one.Just to clarify, the dull yellow areas are raw brass, the bright yellow is a thinner than thin gold plating, the orange spots a protective lacquer above the gold. Any polish, that can shine up the brass, will strip away the gold. So you can have a shiny razor or a partial gold plating but unlickily not both.
It’s most likely from the first production run of 1929-30.
