Might be a Model 5 (or 5-C).  Audio type converter, two (diversity) inputs, 
Space (lower) frequency is fixed, built-in loop supply, four 6Y6-G keyer tubes, 
2AP1A CRT, four 6J6, four 6AL5, two 6AK6 and two 5Y3GT, 19" rack mount, 
10-1/4" high panel.  Will operate either frequency shift for RATT or make-break for 
high speed machine Morse.

I have the 5-C manual available.  $15.00 plus $2.09 Media Mail.

If there was a 5-A or 5-B, I never ran across them.  I got my 5-C out of 
Barksdale AFB in the 60's before I went to Vietnam.
