I have at least two lightly used seppukus that have been recently pulled from working builds. One was on a Flamewheel 450 and mostly used for testing dRonin GPS and althold modes. Also was playing with dRonin dial-a KV by running the 3S motors on 6S. The other was on a RCExplorer Mini Tricopter running a TriFlight branch of dRonin. Triflight is moving back to BetaFlight, so I needed to be able to flash BF on that build, which unfortunately can't be done with a Seppuku. Can send pictures if you like
