    FWIW, I looked at old Radio Amateur Handbooks, the 
SX-111 does not appear in the 1959 edition, but does in the 
1960 one. Note that these handbooks were put to bed the year 
before. In the 1960 catalogue section the SX-111 is 
described as follows:
"Here's the receiver you've been waiting for-a real 
thoroughbred that retains the _the essential performance 
characteristics_ of the renowned SX-101, but at a price than 
can put it in your shack tomorrow!
     Under features its described as having a built-in 
crystal calibrator and a calibration control is included in 
the control list. Tube line up is described as ten tubes 
plus rectifier and regulator.
     Its possible the receiver was actually announced 
mid-year and was changed before the end of year catalogue 
that appears in this book.
     All editions of QST are available to members on the web 
site so one could look through the Hallicrafters advertising 
to find the actual first announcement of the SX-111 to see 
what features it had at that time. I'm still on a dial-up so 
it would take me forever.
     Another FWIW, the 1959 catalogue has the SX-101 Mark 
III, the later book had the SX-101A confirming what someone 
else posted.
