I don't know what a "TO-3" device is, but nobody removed anything
in those photos other than the goop that covered the circuit board.

Focusing just on that Elmos Semiconductor AG IC from this thread:
http://www.bimmerfest.com/forums/sho...d.php?t=309399
It looks like the PN is ELMOS, 10901D, 667A 1302A

It might be a generic or a special chip; I can't find it on the web:
