it might be worth it to draw an black waterline (and move the ship on the template along it) to the waterline the ship had in unfinished state. also, the painting style. and, question, did she receive all 3 (4) props?
All point fixed; about the props (4), Tosa was launched in december 1921, 2 months before beign put on hold and 5 months before beign canceled because of the Washinton Treaty, as all the pics of ships under construction i've seen shows the propellers fitted before launch i assumed that she indeed has all four on place in may 1922.
also, it seems wrong that this ship has the same structure below the bridge on both drawings, but on the completed one suddenly she has doors and windows in it? :O also, on the pics, the 'low' part of the armoured belt at the bow seems a lot shorter.
Both the reference drawing and the official model shows those portholes and doors on that parto of the superstructure, at the same time the picture of the unfinished Tosa shows bare metal plats with riveting visible; my only assumption about it would be that when completion of Tosa was halted the workers roughly plated that section in that crude manner in order to make possible fitting the small open bridge.
Also, fixed the Armour belt.
Emperor_andreas:
The Fujimoto was already done by ALVAMA, as for Hiraga's design i would probably ask Alvama too, because Hiraga's "nelson setup" (aka all main guns forward) eventually evolved in fujimoto's design itself; the other one with 4 guns (and triplets superfiring the twins) should be ok, but i must be sure before to start anything.
