I don't know whether this is good news or not....
FineMolds IJA Type 89 tank kit will not sell separately, this info on ModelGraphix magazine this month. It would be a limited sale like as their A6M2b Zero fighter, not preceding sale like as PitRoad kits.
They might sell separately changing some small detail. But I guess FineMolds knows that they are small company and trust is important small niche market they rely on.
This might be an opinion that is partiality for them.
