I actually picked up a tin of this last week and was very pleasantly surprised. My B&M usually only has one or two tins of each blend on the shelf but for some reason they had an entire box of tins of the Navy Flake on the shelf collecting dust so I decided to try it, especially since it's something I haven't seen online. It made me wonder how long the tins have been aging on the shelf though. Definitely not like other Navy Flakes that have the traditional splash of rum or some cavendish added.
After finally prying open the impossibly tight seal I was treated to the strongest plum smell ever. It was like someone stuffed a bag full of ripe plums and put it over my head! As far as presentation goes I'd give this a big thumbs up, it even had a shiny golden tobacco leaf sticker holding the paper inside closed, too cool. I found it to smoke really cool and the smoke itself feels dry through the nostrils. Tasted like a nice lemongrass and hay, with a subtle sweetness now and then. I was also surprised by the size of the flakes, one is far too much to fit into either of my current pipes. I'd recommend giving it a try... might even pick up a tin to stash away since there were so many available.
