U.S. Army Air Service Search Light

This big bad baby came out of California. I was told it had been a navy searchlight. But when I took it off the truck, I noticed the two brass riveted tags, one from Westinghouse and the other stating US Army Air Service. I figured it pre-dates the Air Corp - my militaria buddy informed me it's a bit older than that...
The light measures about 28" in diameter, big but not huge. It appears to be cast aluminum. It rests on a solid bronze yoke. It has two inner mirrored reflectors made by Bausch and Lomb. The outer convex glass lens is made by Crouse Hinds (I know them, they made explosion proof lighting). The outer faded paint appears to be black with large wide yellow stripes.
I've already started its restoration. It needed a hinge pin for its outer cover. Did that -not too hard. It needs a socket - got that handled too, as I have lots of vtg porcelain sockets, even some large mogul size bulbs.
To you folks out there... Any ideas on further identifying it? Was it actually a searchlight or perhaps a spotlight? Anyone have a vintage pic?
And suggestions for a paint scheme? Back to what it had or what was on it originally?
Oh, and here is the real icing on the cake.... This was one of three that were used to light the Paramount Movie Studios water tower....
