I've looked up some additional info related to the above.  Indeed, the 
VR-3000B did have dual speed operation.  The multi-pin connector on this 
machine also seems to match the one used on the 3000B.  However, this 
machine is not a 'B'.  The 'B' included significant changes to the audio 
section, including a new control panel with a level meter and the addition 
of the cue channel.  The nameplate also confirms that this is not a 'B'.

My conclusion is that the above changes were implemented in late versions of 
the 3000 and then incorporated in the 3000B along with the audio updates.  I 
had never seen a 3000 with these features.

For those that are not familiar with the purpose of the multi-pin connector, 
it allowed an external processing system to be connected which provided full 
playback capability.  The internal playback is intended for "confidence" 
playback only.  The external processor included it's own channel switcher 
(RF from each channel was fed from the multi-pin), a demod, and timebase 
correction.
