There were/are a couple of aerospace surplus shops in the area. Apex and Norton are the ones I'm familiar with. The supply comes from the SoCal aerospace industrial base and a lot of the demand is indeed for movie props. It's a fortuitous pairing - the prop rental business seems to be keeping them going to some extent whereas a lot of industrial surplus businesses in other parts of the country seem to be struggling these days.
