Always worth talking g to one of them… there was a guy here in Newark, NJ. Got to talk to him and know him REAL well between the bike parts and Victrolas, (yes, the crank up kinds) he would do some great work polishing aluminum and plating parts. My wife calls it smoozing. It’s so much easier when you get to talk to someone. The job becomes secondary. They may go out of their way for you too
CHATGPT SAID;
If you mean chrome plating, especially the shiny decorative chrome associated with automobiles, the commercially practical process dates to the mid-1920s.
The key period was 1923–1924, when Colin G. Fink and Charles H. Eldridge in the United States developed a practical chromium electroplating process. At roughly the same time, Erik Liebreich was developing a commercially usable process in Germany. Historical accounts generally date the first commercial electrodeposition of chromium to 1924.
Fink’s process was patented in the United States in 1926, and chrome plating began spreading rapidly through industry during the late 1920s.
For automobiles, the timeline is particularly interesting. Nickel plating dominated before chrome. By the late 1920s, manufacturers began putting a very thin layer of chromium over nickel. Chrome was harder, resisted tarnishing, and kept its bright appearance much better.
So, roughly:
Before ~1925: polished nickel was the common bright automotive finish.
1924–1926: practical commercial chrome plating arrives.
Late 1920s: chrome begins appearing commercially on automobiles and other products.
1930s: chrome becomes extremely common on bumpers, grilles, handles, lamps, trim, and household products.
