WW2 USN L.L. BEAN BAG

What a rare find for today's post !! What we have here is a US Navy Officer's Briefcase, that was made by L.L. Bean for US NAVY officers who were being trained as navigators, to hold their maps, charts, instructions etc...Perhaps the Navy equivalent of the AAF's aviator's kit case !? i don't really know . The bag was designed by Warnie Bean son of the legendary L.L. Warnie already designed,in 1934,the first zippered duffle bag for the company.This example may be a take on their original tote/shopping bag seen in early mail order catalogs ,i don't know!!.Any additional info on the bag,or even pictures,are more than welcome.Who knows!?, the "Bean lady" might once more come to the rescue.......
