[Hallicrafters] Rackmount SX43? ID'ing a Cabinet?

[barry]

hello to the list:
would someone comment on this SX43 i recently acquired?  i've been told
that the SX43 did not come as a rackmount:

black wrinkle front panel w/ what looks like gold lettering for "S 43"
and "HALLICRAFTERS"; rear panel has remains of paper tag stating serial
no. AB-165; no bottom panel, no other IDs that i can see.

what does this cabinet fit?  paper tag inside states "HA-"

item is for sale - looks like a nice straight cabinet, paint is poor;
hinge in nice shape, locking tabs nice, some adhesive residue/dirt;
missing one rubber foot.

tnx in advance,
