Photo of the accessories that would have been shipped with a .38 caliber target revolver in 1947 (note brush with no loop on the end). The same accessories were used through the early 1950s for all target models except the cleaning rod was changed from steel to aluminum.
Also the sight adjusting tool for Post War Transitional target models still having pre war adj rear sights have a very narrowed tip.
Note also that both the mop and brush used brass, not yet aluminum.
The clear plastic bag was not yet in use at that time.
