There is an official case made for the Fuji GF670 version of the Bessa III - the two cameras are identical, and the case fits the Bessa perfectly (I bought one back in July).
Go to "that auction site" and search for the terms "gf670 case". I bought from sk_photo for $99, arrived about a week or so later. Perfect fit, just what I wanted, and I suspect would fit your requirements as well.
That leather bag looks rather thin. It doesn't seem to qualify as "ruggedized". I am looking for something a little more protective ... I think. Is it just the thin leather with no lining/cushoning inside?
Take a look at the Bare Bones Bag at figitalrevolution.com. I have large (BBB2) one for my 35mm film camera and a few lenses, the small one should be fine, and have space for film, etc. Damaso Reyes has a nice review on his blog, in the nice things of 2009: www.damaso.com/blog. Very light, decently-protected- great in the field.

I don't remember offhand exactly what the lining on the inside is like, but on the outside it is just a thin leather. It hugs the camera pretty tight, but comfortably, which allows me to slide it into a jacket pocket. If you're looking for something to protect it against a fall or something, then I would agree this probably isn't the case for that.
I have one these Domke bags (http://www.tiffen.com/displayproduct...temnum=700-52B) that I use for a DSLR or SLR and a lens or two. It's well made and compact; not padded. If you get one, remove the Domke logo from the flap, to make it less visible. I'm haven't done the math, but you might be able to add some padding.
