Sorry - Jackson drive again

[Multi-Volti Devices]

Sorry to keep adding info:

0) Cardboard box has handwritten info " 100-1608, SB-104 vernier".

I don't believe they ever had the part number stamped on them, but I could
be wrong and haven't really scrutinized them. I thought the only Jackson
Brothers ID was "JB" stamped on them.

Again, please rely on the actual physical description I gave previously
(repeated below) to decide if they actually are 100-1608 . There were two
different kinds in the -104, an inner and an outer planetary drive. I never
paid attention to whether the ratio was different because getting them in
the proper order for shaft length was such an obvious requirement to id
them.
