Fantastic discussion in here.
A question for you guys: does anyone know the exact mark and mod of the 8" gun directors fitted to the NORTHAMPTON class? I can't find any specific information on it in Friedman's - all he mentions is how the General Board wanted to add Mark 31 directors to these ships (the type used aboard the NEW ORLEANS class) but that didn't happen, apparently.
Director in question, cropped from 19-N-39220 (dated 14 Dec 1942 during CHICAGO's last refit at Mare Island):

I've uploaded some high-res photos downloaded from NHHC here:

Cheers

Another question. What are the tall objects under the canvas and the directors covered in dials in this photo:
https://cdn.discordapp.com/attachments/ ... nknown.pngThis is cropped from NH 70719 of CHICAGO (CA-29) at Mare Island in 1931 and shows the platform just aft of the number two stack. I think the directors with all the visible dials next to the small gyro repeaters are torpedo directors, but I don't know the mark/mod etc. Friedman mentions this platform as having "altimeters" for anti-aircraft directors (???) before the introduction of the Mark 19 director on these ships, sometimes in this same area (or in other cases atop the mainmast). The drawing of HOUSTON (CA-30) in Friedman's Cruisers shows what look to be short-base rangefinders in this area, but as usual I can't find anymore detail than what's in the photos. Any ideas?
