About as satisfactory as the Halli S-27 from which it was repackaged, 
with improvements that were then injected into the S-36 during the war.  
http://aafradio.org/flightdeck/early.htm has a bit on them.  If you look 
closely at the front panel of my ARR-5 at 
http://aafradio.org/countermeasures/ARR-5.jpg , you will notice that it 
doesn't have a bandspread dial, and that may be a problem for you on 
6M.  The portion of the frequency dial that covers 6M is very small - 
same as the S-27/S-36.  There is also a fairly broad isolation 
(anti-radiation) stage in the front end that needs bypassing...that is 
most easily done by simply inserting a mica capacitor into the tube 
socket between plate and grid - no destructive mods needed.

Having said all that, you probably won't be happy with it if you compare 
it with 6M converters or more modern receivers, but working with WWII 
radios has an aspect of masochism in it that seems to appeal to a lot of 
us. :-)
