Amazingly there is nothing inside that 16pin DIL package. No silicon chip, no

Are you sure? They might have gotten a really good deal on
house-marked Signetics 25120 chips, with not all of the address lines
bonded out.
It could also be a chip used to test an auto-insertion machine or wave
solder machine. If memory serves, they'll use correctly pinned but "fake"
parts to test those processes before moving to the more expensive real
thing.
