This is the place where the majority of the warbird (aircraft that have survived military service) discussions will take place. Specialized forums may be added in the new future

OK, a question for the masses.
Where do you go to get obsoleted
military specs, such as AN-QQ-S-756,
for example?

Sometimes they just show up in your inbox... I'll have a look tomorrow.

I’ve noticed that strange phenomena!
Sorry Bill, I don’t have an IHS account but I do have a 1960 VanDusen catalog of old AN, MS, NAS specs. If you or anyone else needs some info for hardware just let me know.

AN-QQ-S-756 Steel; Chrome-Nickel Molybdenum (4340): Bar and Rod
I cannot find a copy of the spec itself though. I guess you are too close to the cutting edge of technology for the data to catch up! AISI 4340 steel should get you what you need though.
I couldn't find this directly though, I had to do a word search that found a 1950 propeller hub specification that called out this material.

The question that I was trying to solve with that spec
was whether the plate material was rolled or forged.
Appreciate the help!

Sounds like rolled is your answer. Glad to be of some actual help on occasion!
