I bought this Billingham green camera bag in year 2000 from a dealer when I bought a new Mamiya 7 II camera.  It holds that camera most of the time at home.  Sizewise, It also fit my Contax/Leica SLR or Nikon DSLR and Leica M6/M3/Sony A7 A7R II nicely.  I really liked the camera bag looks, feel and size, however, the inner cushion has detenarated  over time.  I once called the Billingham distributor, he was kind enough to offer me a replacement or trade in(that was 3-4 years ago), however, I was in the moving process and the camera bag was packed with boxes that I was not able to send the bag in for that kind offer.  

This is the design generation that inner cushion layer was fixed to the outer layer shell, however, it can be modified with a new cushioned inner layer subclassis either from the original maker or from any Far East bag maker.  It might be even readily available from eBay sellers.  As I am in the downsizing mode, this item is being priced to go for a determined buyer who can find usefulness from this otherwise clean, very lightly used(by me) Billingham camera bag that I paid top dollars for it earlier.
