Jason, I’ve scooted around to some sites and I can’t find any confirmation.It is just my opinion with my experience with Italeri that it is probably an update,but you never know.
I don’t recall Italeri ever doing a 232 6-rad that they could update. I think the only one in plastic before this was the HiPM kit that was not highly regarded. It most likely is an all new kit, but this is just a guess.
