Do you remember MG Mitten back in the 70’s? They were based locally for us in Pasadena, California and were credited with producing some of the first high quality car covers for sports cars. Among other items they sold were racing suits, shift knobs and other cool sports car stuff.
My father bought something from MG Mitten for his 1967 MGB GT on September 28, 1974 although I haven’t been able to confirm the AMCO number so far. Perhaps this is the wood steering wheel? I’ll have to keep looking for this one as the only other possibility is the wooden shift knob but there is no way that was $67.
