At least you have a fairly conventional delay relay, that Amperite. They seem pretty common to find in hamfest junk boxes. I have a chart explaining the nomeclature if you need it to determine normally open/closed and the time specification.
Try finding what I've got in the Collins 300-G (ca. 1946-1952)-- a spring loaded wind-up gear driven set of relay contacts much like a clock. When you turn the transmitter OFF a set of relay contacts closes, triggering a motor on a gear reduction that winds up the "clock" to get it ready for the next time the transmitter is "started," as they say. Upon pulling the start switch, the low voltage / filament circuits ignite, and you can hear the timer ticking down to when it reaches the bottom of the spring load. It comes to rest, keying a set of relay contacts that engergize the high voltage circuits. Amazing stuff, very mechanical.
