That looks in very good condition, a nice find, the rear chassis apron hasn't got any bodge holes in it either, not sure how you're into restoration but if it were mine I would leave as is cosmetically.
Usual ancient capacitor problems for a receiver of that age, the bathtubs might be leaking in both senses plus maybe a few resistors out of spec, if I remember there's a couple on the bias board that can give problems, I seem to remember that the RF gain control is some oddball value.
Sometimes the tuning drive gearbox can be troublesome if it's had a hard life, any backlash will show up when tuning SSB/CW, I stripped the box on the one I had and reset the anti backlash gears, regreased/lubed etc and it was ok, the Xtal filter can be aligned without a sweeper but it's a bit of an art if you've not done one before, when done and the alignment is ok it'll pull in plenty of DX and should be sharp on CW, with a decent antenna.
EDIT: You might have to alter the BFO injection for SSB, gimmick capacitor or whatever.
