I've recently moved from Scotland to Southern France and because I was unable to move my bees here (too much red tape) I've started afresh with 2 new colonies. They came in what look like Dadant hives, but on measuring them they don't seem to match any known hive size. Trouble is I need to buy more frames and don't know what size to get. The Brood Box is (inches) 19.5 x 17 x 12 and the Super is 19.5 x 17 x 7 (inches). Does anyone recognise this hive size and know what size frame will fit (top bee space). Thanks all.
