I'm not so certain about that.  Mine passes 2 tests to say it is a single board type.

1. I checked mine using the AT~S? to get the modem to spit out the serial 
   number.  The number checked with the one on the sticker underneath which 
   iwas said to be unlikely if a daughter board was fitted.

2. I can hear the relay clicking - another indicator that the modem is a 
   single board.

This one has a single 10 pole dip switch plus a 2 pole switch with both
poles locked so they switch together.  The 10 pole switch is black while
the 2 pole switch is red.  I have no info about this switch in the handbook
that I can find.  It is currently set to 1.  I recall a message in the USR
echo saying single board types only had the 10 pole dip switch while the
daughter board types had an extra quad switch - mine is half way there. :-)
 Do you have any info on this switch.

I haven't opened up the case yet.  I presume that the screws are beneath
the rubber feet but how do you get to them?  Are the rubber feet glued on?

Regards ... John
