Item is a M-1951 Korean War Hood Liner. See the photos showing the orange color data. There are actually two different orange stamps. One provides all of the dates, maker etc.
The other talks about how to use the item. Not a lot of use as the stamping is still there and readable.
Would have disappeared if used a lot or laundered. The lace with the two leather keepers great.The fur trim in very good condition with no bare spots.
