@BSZ I think it's Bo Zimmerman's 264, http://ode2commies.blogspot.com/2015/07/completing-set.html.
IMHO together with those featured in Commodore 264, that makes 4 known 264s, out of them at least 3 with different setup. Bo's obviously has no 6529B keyport at all. Michael Tomczyk's one has a dead-bugged 6529B, similarly to Crock's V364. And, finally, also Crock's 264 already has a 6529B as would be usual for a production Plus/4 (which likely makes it a late 264 prototype). Interestingly, assy numbers are all identical  . I couldn't recognize an EMI filter around the joystick ports on either of the boards (a standard feat for the production Plus/4, damping the buffered data bus line output signals), which suggests that these are still not fully identical to the production model, not even Crock's late one.
