Selecting another station was a noisy business and flywheel tuning allowed the dial to be traversed quickly with a flick of the wrist. Those flywheels were heavy and mounted in ball bearings...
The trouble with trying to obtain spare parts for radios is mostly you can't. The manufacturer uses mostly bought-in standard electronic and hardware components and makes as little as possible, apart from the cabinet, the circuit boards and a few other bits and pieces and then will assemble what is generally regarded as a consumable item. The manufacturer's interest fades quickly when the warranty expires. Whatever (few) parts remain will be priced not to sell in order to build in obsolescence.
It is mostly expected that minor repairs will be handled by local repairers using standard parts until it becomes uneconomic or obsolete.
It might be possible to locate another plastic "flywheel" but searching would be a mammoth task. The number might not be a part number, might have been made by anyone and Proton is such a popular brand, model, type a search would not be easy.
The best alternative is to repair the original, adapt something else to do the same job or have a replacement made or devise another method of doing the same job.
