Herve asks:
But I know there are Brother Adam adepts
(disciples ?) on the list who may find the text faster
than me.

I believe Brother Adam preferred the Dadant jumbo which would be my choice
but because of the weight involved and availability I use the standard
Langstroth but I and am considering the 18 x 18 mediums (6 and a quarter in.
high) of which I have got a couple hundred boxes in the shed for my two
queen hives. These were the size Farrar, Moeller and Harp preferred.
You can read about their use if you have got access to old Gleanings in Bee
Culture magazines :

"Gleanings in Bee Culture (Nov. 1965) pg.  679
"The Two queen system Simplified" by Floyd E. Moeller & Emmett R. Sharp.

Is a queen excluder available for the 18 by 18 size overseas as I believe
long ago Chris said the size was in use in the U.K. but not in medium depth
we use in the U.S..  I believe from memory.
