Request of US translation of Japanese captured document: CINCPAC-CINCPAO Special translation #73

[skultew]

Hello everyone. I write this thread as request to community about US translation of captured Japanese document called: "Aircraft Section, Supply Depot, Study of Increase of Armor, Bullet-Proofing, Fire Extinguishing Equipment, and Armament of Various Aircraft, Japanese Army Air Force (1944) [CINCPAC-CINCPOA Special Translation #73]"

If anyone have it or can help with searching of this document it would be very nice

The document itself is placed in Japanese NDL but it starts from page 41 while most interesting translations are placed in 1-40 pages

国立国会図書館デジタルコレクション

Its mention was found in book Exploding fuel tanks where it is used as source in chapter 6 talking about army aircraft protection.

Interesting that it looks like this document has information about nitrogen fire extinguishers for army planes like Ki-49, Ki-21, Ki-51.

I couldn't find mention of fire extinguishers on this planes (only for Ki-67 was found) in available Japanese documents so information in this Special Translation #73 looks extremely rare and useful.

Thank you for interesting and helping

You could try these people. If you can find a complete translation I am sure others here would like to see it.

Hey skultew,

If I am understanding correctly what you would like to do?

On the screen below, enter 109 in the box for "Frame number".

Next, go over to the right and all the way down to where you will see the following, where it allows you to select "JPG" or "PDF", "Standard resolution" or "High resolution", and "All frames" or "Specify range". Make your selections, then press "download". This should download all 109 pages of the document.

That would work except the report jumps from page 5 to page 41 . . . 6 thru 40 are not there

 

[ThomasP]

Whoops, sorry, I misunderstood.

Hmmm, pages 48 thru 64 appear to be missing also.

Thank you but unfortunately I haven't found this document in the list.

The National Archive might have those missing pages in the Record Group 243: Records of the U.S. Strategic Bombing Survey, the problem is it's a huge among of rolls without indexing and their documents don't necessary follow a chronological order.
Note: the individual image files (tif) are huge but the last part should have a link to a pdf,, that to be fair you'll need to convert into jpg's or cbz to make the search faster, the original pdf can be awfully slow.
ie: https://catalog.archives.gov/id/406610526 → M1652-0057.pdf, Portable Document File (PDF), 355 MB

I thought same so searched through this archive. Needed document are placed in Intelligence Library Documents, 1932-47: IIId. 57-64 (1 of 2) but it is also missing that pages and it is similar to NDL file

I have not downloaded any documents from the USN archives but do know that many of the records at AFHRA https://www.dafhistory.af.mil are incorrectly indexed. Obviously some of the persons tasked with making the indexes in the 50s did not care what they wrote. Also many of the records are out of order. I strongly suspect that this was caused when the other persons tasked with loading the microfilm camera dropped a bundle and, instead of resetting the files in index order, just picked them up and loaded them unsorted. Thirdly there are some microfilms that suggest person(s) loading two machines dropped bundles and mixed the bundles. For example some of the General Kenny microfilm files are missing a large batch of pages but the microfilm contains a large number of files that are not in the index.

For this reason I would suggest that, if you can find the "original" reel that contains Special translation #73, you review the full microfilm record to find if the pages are out of order. I would suggest you do this with both NARA and Navy microfilms.

Further to the above. When the AF microfilmed the files they photographed both sides of every page. When the AF digitized the microfilm reels they removed all the blank pages from the pdf. The last few frames of every film contained the index which naturally identifies the content by (intended) frame number. Deleting the blank pages made this index (and all the indexes at https://afhistory.org) which are transcribed from the film indexes essentially next to useless.

Furthermore there are many of the microfilm frames where the person(a) doing the photography massively over exposed the frame and the page is effectively a blank page.
