I am relatively new to ACMOC, so please forgive me if this is the bizillionth time this has been asked: is anyone out there making reproduction fuel tanks for the Cat Thirty these days? I have a 1929 that could sure use one. I have been thinking about looking for a metal fabricator who could make one, but am not exactly sure what the filler neck and cap look like, or where I could come up with ones I could use on a new tank. Thanks!
