Bone Dry Coolant Reservoir...HELP

Fluid has to go somewhere and as the cooling system only cools the exhaust ports, can't imagine it going "down" into the engine. No doubt I am wrong about the nature of the cooling system, but that is my understanding. As such would have to be leaking out. I would refill and start it up and monitor. You do have a service manual, don't you?

There is a discussion here about a "porous cylinder head" that actually allowed coolant to seep into the cylinder. Apparently, they aerate the metal when casting the heads to make it lighter, and occasionally that creates passages large enough to allow liquid transfer while appearing to maintain pressure. While this seems unlikely...if you really can't find any other leak, this might be worth investigating.
