This is a Midtex
655-11T300 120V 5 Amp Double Pole - Double Throw TIME DELAY RELAY
with an Plug In base

This TD relay was in a drawer that it barely fit into and the sides of the relay were scrapped when the drawer was opened and closed.
This TD relay is new, but is cosmetically a bit rough. The previous owner was Sun Microsystems and this was a spare part. Unused.  

These are factory new parts. They have never been installed and have not been recovered from manufactured electronic components.
