12 KODAK INFRA RED EXTRA RAPID BACKED 2.5 x 3.5" GLASS PLATES . A rare find . I can`t find a date on the box but other items I got at the same time were circa 1970 so i`ll go with that ...... so no guarantees ..... and NO idea where it has been stored and I`m not going to pretend I do ( unlike some :o) the box is SEALED so totally unused , not tampered with !!! Free UK P&P ( costing me £4 ) .
