Arnaud sent me this as a gift. "BSA Saftipaste" Some sort of metal polishing/ cleaning paste. When I removed the lid, it smells/looks/feels like the orange colour cutting paste that we know. Ron
It's a gun preservative paste...The tube you have looks to date from a later period than that described below...Ian
['A gun preserver which was much in vogue in this country just after World War I was a British product known as B.S.A. Safti-Paste. The initials stand for the maker, the well known firm of Birmingham Small Arms Company. This was much praised and recommended by gun editors and experts. It was said to be a good safe preventer of corrosion, and a boon to the lazy man, as all that was necessary was to coat the bore with this after shooting and then forget the gun until the next time it was wanted for shooting....']....
