The good stuff! SR4759 and 8 unopened pounds of it at that!
Pretty scarce stuff anymore, I think it fits in with the rarity of hens teeth and rocking horse poo! I managed to get a few 1lb'ers of it a few years ago but have never laid eyes on an 8lb'er of it.
Rest of the show was very dismal. This made the $12 ticket worth it. Found a neat 20rd packet of .303 British, 1950 FN production too. Labeled as Bren MG ammo.
