This Brill Bros. G-1 I got off eBay has a label modification I've never seen before. The cleaning instruction label was placed on top of the manufacturers' label, then both were sewn in as one piece. When I fold back the top of the cleaning label, a (contract?) number is visible, but it also appears to have been blacked out at some point with some kind of marker. So, does this mean it was a jacket manufactured for issue to the navy, but was re-labeled for sale on the civilian market? Does the tag indicate it was an E series, manufactured in 1971? Any information would be appreciated!
