this is a common newer triac package.  it is called a TO-3 Fastpack
by at least one manufacturer.  notice the base outline is just like a
TO-3 transistor.

Digi-key list quite a few triacs in this package made by Teccor.  The
most expensive is $13.40.  I would suggest you contact Teccor, as they
probably originated the triac you mention.  I don't have their address,
I believe they are in eastern Pennsylvania.

Good luck--if I find the part # I'll get back to you.
