Handspring 1/2 on, 1/2
Handspring 1/2 on, 1/2 off
Tsukahara 1/2 off
The valuation of this vault is rather unusual in that it is worth 0.8 more than the simple repulsion off the table, which is an uncharacteristically large increase for an extra 1/2 twist, especially in an era where the WTC is trying to keep increases at a regular interval of 0.4 per additional half twist.
This was the compulsory vault at the 1980 Olympics.
Note that this vault begins like a Tsukahara-family vault would, but it is not officially classified with the Tsukaharas because it does not feature a salto in post-flight, which is also part of the requirement to get into the Tsukahara family. You just kind of flop off the table instead.
