Nice kit, indeed, but I've changed the title of this thread to reflect some change in my plan.
It turns out that the kit, as packaged by Eduard, is really more of a Type 24 than the 18. I base this on the radio compartment door and right side cockpit entry hatch. These were not (usually, at any rate) found on the Type 18 according to the research I've been doing.
Changing to a 24 also gives me some more flexibility in markings choices, and I intend to revamp the whole project to reflect this change.
