* note:  

Otsu was manufactured from s/n 1356 beginning in August 1943 (after ko). A lot of references imply that otsu had 40mm wing armament 
as standard. It could be fitted as 'special equipment' to this version but the standard otsu configuration was cowling 12.7 weapons 
only and no wing armament (same as Hayabusa).

Hei was manufactured from s/n 1750 beginning in April 1944 (this was the version with 4 x 12.7).

I don't know why early references confused the sequence but can only speculate a belief at that time that the 40mm was introduced as a 
late-war anti-B-29 weapon rather than during the late summer of 1943. What is apparent from intelligence reports is that some otsu 
(as manufactured) were retro-fitted with 12.7 wing armament, becoming effectively hei. There were a series of armament trials held 
between otsu and hei manufacture that effectively decided the subsequent hei configuration.
