Ryan Toews has recently completed and shared a very fine analysis illustrating a number of details of the Aichi D3A1 'Val', Type 99 Carrier Bomber (99 Shiki Kanjoh Bakugeki-ki - 九九式艦上爆撃機) known as 99 Kanbaku (九九艦爆) with an important goal being to compile a list of modifications and/or additions applicable to the 1/48 Hasegawa kit. The 19-page PDF 'Detailing the D3A1' presents full text with photos, schematics and colour data (sample page thumbnail below) and is available from Ryan on request. A direct link for requesting this PDF has now been added to the sidebar below the blog archive.
With special thanks to Ryan for sharing this excellent and valuable study and very kindly offering it to others via Aviation of Japan.
