These parts are not dysfunctional, but it falls under the classification of poor quality, especially for the appearance of obvious parts on the dash panel in the cockpit. These parts would never pass muster in a concours show. Original part on left, replacement part on right.

The "S" and "C" logo on face of the knobs for Start and Choke was originally molded in depression and filled with white enamel. Replacement parts have this logo printed on flush surface, guaranteed to wear off in due time. Original bezels were chrome plated and polished. These current replacement parts are die cast pot metal with molding marks, no plating, guaranteed to be corroding when shipped and corroding worse with time in service. The replacement bezels are also different shape, thicker with wider chamfrer giving a heavier appearance, out of character for the light weight roadster.

Some (if not all) of these replacement cables will be longer than original issue, likely intended to be used for multiple applications with various lengths. That is not particularly bad, as they can easily be trimmed to length with a thin abrasive wheel (standard procedure for replacement parts). The Choke cable now has twist left to lock function where original parts would twist right to lock (or some early issue parts would lock when pulled and push to unlock). Those are not necessarily concours issues.

Picture above shows replacement Start and Choke cables installed in my car. If you change both at the same time, at least they will match, but they look like 60 years old when new. The Choke cable is new in late July 2019. The Start cable was new in May 2015, the "S" logo being long since worn away. Having unmarked knobs is not good when these controls have often switched position in various cars. That is a functional problem. You can buy replacement knobs. Crush the old knob in a vice to break it for removal, then glue the new knob in place with industrial epoxy (like JB Weld for instance). Logo on the current replacement knobs may also be printed rather than embossed and filled.
