These are appearently non-military related papers.
The upper and middle ones are for Post Office Fixed Term Deposit certification and it is possible these are post ww2 ones.
The third is a written instruction regarding shipping of goods from a company probably in Saipan. The nature of the goods were not stated.

On the last lines on the third document are the names of two vessels; Yokohama Maru and Amagi Maru. Both were NYK ships.
Yokohama Maru was sunk off Salamaua in New Guinea on March 10th 1942 and from this the document presumed to be issued sometime before the height of the war.

Hi Micdrow,
>This info came from the book Japanese Aircraft Equipment 1940-1945 by Robert C Mikesh. Has lot of info on gauges and stuff.
Since the topic surfaced in this thread: http://www.ww2aircraft.net/forum/polls/f4f-wildcat-versus-p-40e-tomahawk-13281-3.html#post378507 ... does Mikesh mention if the coloured sectors on the manifold pressure gauges were "generic" or if they were added to match the operating limits of the aircraft types they were installed in?
The reason I ask is that the A6M3 reportedly has a +300 mm Hg war emergency power setting, but contemporary photographs of an example tested by the US show a coloured sector ending at +250 mm Hg.
Of course, this difference would have an impact on the performance of the type.

Henning (HoHun)
