I think you are going to need a better term than "old Jumbo" for anyone to know which hive yiou are talking about. That has about as clear a definition to me as "CCD" or "Disappearing Disease".
I have hives with "Jumbo" 11 1/4" deep frames that have the same frootprint as a common Langstroth hives except that the brood boxes are deep enough to accommodate the frames, about 11 5/8" deep. I also have Brother Adam hives that measure 19 7/8" square or thee abouts with the same depth.
And then thee are all of the English and European size hives. Here is a paste and copy from an old Beesource post:

Historically in North America there were two large brood frame designs, the Dadant and the Langstroth Jumbo. There is no "Dadant Jumbo."
The standard Dadant brood frame (like the one used by Br. Adam) has the dimensions 17 5/8 * 11 1/4 inches. There are 11 of these in the Modified Dadant hive, and 12 in the Buckfast Dadant hive. The frames are spaced wider than Langstroth, on 1 1/2" centers (an important difference).
The Langstroth brood frame is 17 5/8 * 9 1/8 in. Normally used in an 8 or 10 frame configuration. (One of the reasons why the 10 fr. hive became popular is because the 8-fr. had a tendency to tip over.) Frame spacing is 1 3/8" center to center.
The Langstroth Jumbo brood frame is deeper, at 11 1/4", making it similar to the Dadant brood frame, but it retains the narrower spacing.
In Britain, many users of National Hives have gone to a 3 1/2 inch-deeper version of the British Standard brood frame, at 14 x 12 in. to allow for a larger continuous brood comb area. This would be analogous to the Jumbo Langstroth frame.
20 years ago you could still get Lang. Jumbo frames and bodies from at least one supplier in Quebec but now they aren't in the North American catalogs anymore that I know of. Posts: 131 | From: Wakefield, MA, USA | Registered: Jun 2004 | IP: Logged | Report this post to a Moderator
