According to my sources all 3 carried 1 double-torpedo launcher, 53cm. I'm specifically looking for plan views, hull shapes.

That's fantastic, thank you Fontessa! I didn't realize it had double-twin mounts! -The Pete's (Mitsubishi F1M2) are also a surprise, I thought they carried 2 Kawanishi E7K Alf's. (I prefer the Pete's!)

You are correct. Firstly 2 Aif''s were installed. They were replaced with 2 Pete's later.
