Your title mentions oil bath filters (air cleaners). No one makes reproductions. You best bet would be eBay or the Swap Meet or vendors that sell used parts.

If, however, you are looking for the original, stock air-cleaner for a 1954 235, Jim Carter sells a reproduction (he also sells used oil bath air cleaners). Used stock air cleaners are getting harder to find - more people are now appreciating how they look, especially on dual-carb set-ups (same goes for oil-bath cleaners).
