Check out cameraleather.com I have used their products on several cameras and it looks good. The most recent was red snake skin for a Konica TC that I picked up dirt cheap with a bunch of lenses and it looks fabulous. They have a cover that is know as Minolta black that has good texture close to factory and is really grippy.
I have a soft spot for the pre MC lenses and have started collecting them. They can have a real creamy quality to them as well as being pin sharp.
