As said, a tired Momo steering wheel,15,” which I believe converts to 380mm. Momo number stamped on one of the spokes is “TYPA38". As the picture shows, It needs recovering. Looks like a 4 spoke Alpina wheel, but not drilled for the Alpina padded horn ring. The extra holes for the Alpina wheel can easily be drilled into it. First $135 shipped in the lower 48.
