Well, you're not seeing things here, but I can't attest to what's happening elsewhereThanks for confirming I'm not seeing things.
While it would seem to make sense to handle the entirety of an installation at one time, Japanese production, resource, infrastructure, and supply chain issues undoubtedly came into play. The installation of radar aboard their destroyers is an example. Foremasts to carry the Type 22 radar were being modified as early as mid-1943, but the radar itself often wasn't installed until months later.
So, a partial installation was entirely feasible, IMHO.
