On eBay I’m seeing copies of escape map pouches that are really well done, at least for re-enactment. There were different versions, but currently I see only one kind. You can also get the French banknotes, escape saw blade and escape compass to go with it. This is the link to the seller’s page if you’re interested. As long as these items are being sold as replicas, it’s quite harmless, and as such they are great for living history displays and re-enactment. But sooner or later these items will be ‘aged’ and passed off as originals, or ‘not sure how old this is’ etc.
