I have a '33 that was rebranded as an Anderson-Jacobson unit and has
an AJ acoustic coupler built into the right-hand cover panel just as
you describe.

The modem plugs into the 20mA loop at the Molex connector bank at the
back of the '33 with a single connector and gets power and transmit
and receive loop over that single connection.

The LOCAL / LINE switch was relocated to the panel of this modem and
then the front plate (below the keyboard) of the '33 has no hole where
the local/line switch would normally be located.  That plate is then
logo'd with the Anderson-Jacobson "waveform" logo and the 33's lid over
the typing mechanism has an AJ decal stuck over where the Teletype logo
is normally found.

This '33 also has a slashed-oh on the keyboard and typewheel--  as
opposed to the more common slashed-zero.

I'll take a couple pictures and send them to the list as soon as I can.
