Cannot read Japanese, it looked like five degrees on the drawings. My fault.
No, no, you're quite right. The original limit was at -5 degrees. When it came time to modernize their ships, the Japanese took a unique approach to increasing their gun elevation; they lowered the trunnions and working platform. This allowed them to get 43deg elevation, but it cost a couple degrees of depression, which I doubt they missed.
If you don't mind, I'd be interested in any material you have on the original design. Could you send me an e-mail, my screen name @alltel.net ? Thanks much.

Wasn't on this one battle, due to such close quarters action, that in one of the USN DD's one member of the crew shot off a Japanese searchlight with a rifle?????? Just curious... I think I've read that somewhere.

I suspect the sailor give his own marksmenship too much credit. It seems hard to believe that in the blinding face of a lit searchlight he could have aimed effectively at the actual bulb to put it out.

They probably also put in entirely new elevation gear, got rid of the original all angle loading and substituted with fixed angle loading.

From memory, it was fixed loading at +5deg.
