WWII vintage Red Cross knitting pattern leaflets, uniform sweaters, knit helmets for soliders

Lot of a dozen assorted 40s vintage knitting patterns leaflets for sweaters, vests etc. needed by WWII soldiers, published by the Red Cross.

These have some wear but are complete with each pattern in full, a wonderful resource for period costumers, historical re-enactors, or just someone who remembers these well-made 40s warmers, and wants a sweater / socks / knitted helmet like the ones grandpa had.
