Yeah I guess I just rub them out in case someone wanted to clone the plate. Not sure it is really worthwhile but it only takes a minute.
The bag is a Gearsack, it's an Australian make. I don't think they are made any more, I bought it years ago when I bought a brand new Africa Twin - that's how long ago.
It is still, literally, like new. A supern bit of kit, absolutely love it.
