Thanks for the comment, Robert !
yes the bees are nice and gentle, they come from good stock, from Paul Metcalf, Norfolk.
I wanted to show how I had adapted national frames to fit my commercial 16 x 10 brood box.
I am still on the practical beekeeping course at Easton college, and get to manipulate several different hives each week, most of them are all different types, as this is a teaching apiary. there are bees in a skep, nationals, commercials, dadants, langstroths, WBC's plus a few rare types of hive from history.some have already got five supers on!! (motor on extractor blew, and Paul thinks 'on the hive' is the best place to keep supers ready for extraction) all but one of the hives are very well behaved, and this one is up for re-queening.
It's a steep learning curve, ain't it? ;)
