SAN FRANCISCO (UPI) -The National Hockey League Board of Governors is all that stands between the Oakland Seals and a supply of white hockey skates.

The board must consider the proposed sale of the Seals to Charles O. Finley, the flamboyant owner of baseball's Oakland A's, whose request to purchase the hockey club was approved Tuesday by San Francisco Superior Court Judge Robert Schnacke.

Finley said he would like to duplicate a couple of his baseball gimmicks by adorning the Seals in white skates and displaying a pair of live seals as mascots as home games. Finley's A's wear white shoes on the baseball field and have a mule as mascot.

The insurance millionaire has offered to pay $2.5 million in cash, to take over more than $900,000 in Seals debts and to waive about $700,000 coming to the club through the NHL expansion setup.

The Finley offer was made possible ‘ when Barry Van Gerbig regained control of the Seals.

The Florida millionaire, who financed NHL expansion to Oakland three seasons ago, sold the club to Trans-National Communications before the 1969-70 season. But Schnacke ruled June 1 that Trans-National had defaulted on loan payments and Van Gerbig thus was able to open the door to Finley.
