As I understand it the D or DS designations refer to the version with the small round dial like the one I have or perhaps I'm just confused? I don't think I got a direct response back then

Yes, the D and DS are the later ones, which are completely different. They have a large central tuning knob with a concentric BS knob and two small rectangular windows, one for main tuning and one for BS. Despite the presence of a stabiliser in the DS, it still drifted and there was chronic 'pulling' of the local osc on strong signals on the higher bands which made SSB reception interesting unless you kept the RF gain low. Not my photo.
