Hi Folks...I need some help with a haversack i purchased on ebay. It looks to be unissued and looked really good in the photos. It was described as having a few small rust spots here and there from improper storage however when i got it the rust spots were obviously caused by the buckles which had small areas of rust. The haversack says Boyt 42 on the back I never made the connection with the rust spots on the sack because I assumed the buckles would have been brass since the sack was made in 1942. So finally my question. At what point in time did the straps start coming out with tin buckles (and strap tips as well)or did it depend on the manufacturer.
