I just signed up a few minutes ago .....
I bought two of your canvas bags back in the early 80s when I was just starting my new hobby, since then they have become worn and faded but I have never seen the need to replace them since they have always protected my gear even after the big bag was thrown to the floor , the board in the bottom broke and I cracked a filter but the three Nikons were just fine, in fact I still have those too, maybe someday I'll go digital but for now your bags and my cameras just keep on ticking ....
the bags look like your F10 and F8, but I thought the big one was an F2
I can't recall it's been too long since I had to worry about it.
Thanks for a great, well made, long lived product
