Have you ever seen a Bronica model C in BLACK?

It's common to see a Bronica model C in silver, but rarely in BLACK. There're very few pictures on Internet about it, and I have never seen a black one on second-hand markets.
It is said that a particle of the models have '1000' marked on the shutter dial, but as far as I can see, these are exclusive to the BLACK models.
These BLACK models seem to be mysterious and hard to find.How many of them were made? And is there anything else different?View attachment 364940

See the "Bronica Product Guide" at Pacific Rim Camera's library of camera literature: https://www.pacificrimcamera.com/rl/rlBronicash.htm

This guide was distributed by EPOI, the US importer. On the cover and page 4 there are pictures of a Bronica C in black. On page 4 the footnote says that Bronica C sold in the Japanese market had a max shutter speed of 1/500 and those sold for export had 1/1000. I don't have a Bronica C, but I don't think the color of the trim is correlated to the shutter speed. It may be that one of the colors was more common in domestic vs export markets. Many Japan-market cameras can now be found outside Japan (sales from travelers, ebay, etc).
