What would be the Elmo SC 18 HiVision twin?

[Stuart Budd]

Quite a neat machine is the SC-18 M 2 Track. Built in viewer and twin audio magnetic sound. Accommodates 600ft. But which Elmo regular projector would it be based on? An ST600 M Twin Track!
It's just incase I hanker for another Elmo but feel the GS range a little too complex. I wouldn't want to step on the HiVis toes.

Possibly the HiVision SC-30?

The SC 30 seems to be it's own beast. Spools at 90° to each other. Odd and smart. But I was woundering more to which ST model was similar or even same as. The ST600 feature set and film path look like that of the SC 18. I do like the SC 18. Gave it a quick blast this evening with Road Runner Guided Muscle. Sound was a bit off at the beginning so may try and re record it.
