Last weekend at the Mena swapfest I bought a military transistor testet
Model TT-22 made by Abbey Electronics, L.I. NY in 1968. It uses four
Eveready Alkaline 1/2 D cells N0. E94 1.5 volts. I've never seen or heard
of these runts before I got this thing. Google isn't much help. Any tips
or help appreciated.

Apparently Sanyo makes NiCd (rechargeable) 1/2 D cells. You might try
their web site. They supply batteries to many products that use "1/2D
Battery Sticks".

I've a guide that lists that battery to be registered as NEDA # 927
(and no equivalent Mil #, or Burgess, or Mallory, Ray-O-Vac etc.)

....and Google was useless for me to go further too; no, it's not
'National Eating Disorders Association', it's the National Electronic
Distributors Association; but I didn't see any spec information on
their web site.

Hank, how are the cells arranged in the unit? If they are all in line
then it may be possible to assemble a cluster of 4 AA Alkaline cells to
fit in that space. They would have a capacity not unlike four 1/2D
carbon-zinc cells.

The 4 batteries are in series in a cambric (sp?) tube. There's room for a
number of mods that I could do to get 6 volts but I thought I might be able
to keep it original, its in very nice shape with all accessories. If I
could find a junker or another cambric tube I might be able to install 4
standard D cells.

Perhaps you could hide a 6V lithium battery in there somewhere?
