I recently picked up this box. On the base it has an H and BFL 4 burnt in but I guess the brand must have been slightly angled and so the date and box number are missing. The only other markings are an FFE stencil on one side that reads TN/FFE/EK though it could be ITN/FFE/EK . It's 9" long and 9 1/4" tall and 7 1/4" wide. It is exactly the same construction as the late war H51 and the wood used is the same as 45 dated H51's so it must date from the mid to late 40's. Does any one know where it could have been FFE'd which could point me in the direction of Army / Navy or Air force? Any help much appreciated. Cheers Gary
