Yes, that is about how I figured it should be.

Ah, these numbers must start a LOT later than the US bridgeports, if
J350 has the electronic power feed. The gearbox power feed may have
been added later. (It usually requires the X leadscrew to be changed,
if there is any fudging there, it pretty much assures it was added later).
