I'm wondering if the second photo could be a metrogon? It sure looks like one, and that was a popular lens for aerial photography.

As to the third photograph, that's clearly three 121mm f8's connected to give a 363mm lens at f24.

I am guessing, based on that red circle on the front standard, that the 8x10 was rebadged as Orbit, either by Burke & James or by Arkay. They were manufactured, according to Lynn Jones, by Calumet. I have the Arkay version manufactured in 1978, all 19 lbs. without lens.

Look under the rear standard near the locking lever for rotating the standard. There may be a tag with the serial number, year of manufacture, and vendor identity.
