There were 5 different patterns of brushes issued for the thong and oiler from WW1 till the 1960s Bill Ricca has posted previously.The nickel plated oilers stayed in service up into the 60s with NG units.If it was in the storeroom it was issued till there were no more.Brass pull throughs are most likely pre-WW2.The WW2 and some 1930s brushes I have that came out of dated pkgs. were all steel cored with pig bristle brushes.The WW2 Baracks rods brushes in pkg. I have were brass with brass bristles but are longer than the ones for the oiler by about a 1/4 inch.The pull through with the white cord the cord is a replacement.
A man with a sword may talk of peace.A man with out a sword may talk of peace,but he must talk very fast indeed.
