Stop the presses! In my haste, I overlooked the 4-400 in my HB-3 manuals or
maybe it's misfiled. In the Transmitting Volume, just before the 9C25 and
just after the 3B28 I found it! I'd say it's out of place in my books. The
date of production listed at the bottom of the page is 9/62, so that would
jive with the BTA-1R2.
Actually, this deepens the Mystery - both my HB3s reach from the late
30s to the early 60s... they were updated by subscription, so it depended
on who had them as to exactly which updates...
