Thanks for making the C-184 information available.  The C-184 works with
transmitters BC-AE-230 and later (except BC-AF-230, which used the similar
C-182).  The standard crystal frequency is 4495 kHz.

Speaking of the BC-AF-230:
By the time of the BC-AE models, the SCR-183 transmitter designs had pretty
much been set, notwithstanding variations in control and sidetone, etc.
It's curious that Western Electric's first dabble in SCR-183, the
SCR-AF-183, would be a "throw-back" to the early, first design with all its
flaws.  I think the W.E. engineers must have known this, because they
devised an exclusion device to prevent earlier and later coils to be used
with BC-AF-230.  I have a -AF transmitter here and it looks like the first
230, right down to the stack of paper coil charts.  No coil for it, of
course :-D.  
Any speculations about why they would have done this?
Intended as an "export" model??
