MFC in my humble opinion.

MFC made a bunch of slags--some very bigs ones as well--I do not recall the largest size that they made--very big is all that I can say.

They are one of the oldest--if not the oldest machine made ( they did hand-gatherered Machine rounded )marble company in the good ole USA.

Any MFC is a good find--a true Antique.

Nice find!!

Marble--On!!
