1947-48 Tacoma Mountaineers (PCBL)
Saw his name written as "Tom Wark" in one encyclopedia, but not sure if this is accurate. Name listed as "Al Wark" in the below-listed Eugene Guard. He is not the brother of Roy Wark who also played in the PCBL.
There is a gentleman named Allen Alexander Wark (1919-1986) that could be the answer, but I do not know.
