MPN11 (#5),
Was that all that was left of it when you'd finished with it ?
Kept my button stick for years: it must be somewhere around the house still. It was second-hand when issued to me in 1941, and had the service number of the original owner (900,000 series) stamped on it. For that matter, my issue tunic was "part-worn", as well. Often wondered what happened to the first (?) owners.
Waste not, want not !
