Hi Bob/s, and all,
Not familar with it, but viewed the ebay pic's. It looks like
only the electronics/film medium there with the case opened.
The larger round oblong object looks to be the film container.
Presume the actual sensors are (not there) normally separate
and connected via a cable plug-in on the case. So, its without
the sensors I presume.
Note the same seller has two SMA-2's up for bid also, but they
appear to be without any sensors either. Ebay #1923227423
Take care, Meredith
