I'm not sure, but think that's a 1F312. The film is "Thicker Than Water" (1935). It's a Laurel & Hardy short subject comedy also starring Daphne Pollard and James Finlayson. I'm guessing the clock was painted white to accommodate the scene which portrays a hospital.
In the scene, Stanley is visiting Ollie in the hospital after he was injured by his wife clunking him over the head with a frying pan. She was angry with Ollie after he drained their joint savings account, and paid $290.00 for a Grandfather clock he won at an auction.
