T-13
From Sega Retro
Not sure the Sega Table T1 was released with Seesaw Jump as it was released with the T2 as seen on advertisement. The T1 should refer to the fat table released in 1974 with Sega Table Hockey and seen running with Sega Table Baseball later. https://flyers.arcade-museum.com/?page=flyer&db=videodb&id=3025&image=6
