Re: jumbo or extra-large hive bodies - source?
The jumbo's were not meant to be picked up and moved around. They were considered to be brood nest with stores and left in place. The supers were stacked up on top for honey harvesting. Perhaps Michael Bush has a link to the old writings stating the reasons/theories for using them. I think I remember that they were over wintered in the single jumbo Dadant boxes, being large enough for the winter cluster with stores.
