I recently purchased a Pattern 1907 bayonet manufactered by Lithgowicon in 1943. The press stud or locking bolt in the pommel will not move, most likely frozen in position due to oxidation.

My question is what is the preferred method to fixinf this problem? Is any type of commercial penetrating oil OK to use?
