I suggest you look at the Roadrunner bag VO sells. It was made with grommeted holes in the back which match the holes in the VO decailluer.
I see they are sold out, but give them a call and see when they will be in. I believe they are MUSA, so the wait should be short.
The VO decailluer is too short for standard Berthoud type bag ad does not reach the leather strip typically on the back of the bag..
