The "Winner" model was discontinued some 25 years ago. I have a drawing for it, but have never actually seen one. I do know a few things about it...that it's a wonderful toilet--a bronze "throne" that should last at least 100 years, and that parts and rebuild kits are still available for it--and prob'ly always will be. I'm 90% certain that lanolin is the best lubricant for the leathers, but I'd rather W-C advise you. Their phone # is 800-521-3032 Let me know what they say?
