A fuse rated at 50A likely would mean a MAXI-fuse. The description of "big-orange fuse" completely convinces me that it is definitely not an ATC/ATO or Euro-blade fuse. I don't know for sure but I am just saying that ATC, ATO and Euro-blade fuses are limited to 30A.
I don't think you could get a camera in there, Peter. As I understand it, the fuse is above the glovebox and above and behind the fuse block further up in the dash in a vertical position. You are going to have to remove the glove box. That is to say, I think the wires in the foreground of the picture on Bimmerforums are the wires coming out of the back of the fuse block.
I get my fuses at West Marine but there are numerous on-line and retail sources. A boat supply store will definitely have it (if it is in stock is another matter) and an auto parts store should.
MAXI on the left, ATC/ATO (similar to Euro-blade) on the right:
