I chatted with Dave Layson about that as well as my neighbor who owns a mold/tool and dye shop. Here in the US, stamping dies cost around $10,000 each and trim dyes about the same. Take that x2 for left and right. The stamping, trimming, raw material, and labor to manufacture is the cheap part. One year only. Oh and someone would need to loan a perfect bezel for a pattern.
