Hi Folks,
Thought that you all might be interested in this thread that I had posted on another site and with the help of a Japanese collector (of Japanese weapons, kit and ordnance) residing in the US have managed to come up with the following about one of my latest acquisitions.
Here is a Japanese Navy Igniter Pad which was tied to the bottom of the Bag Charge for the 15cm/50cal 41st Year Naval Gun. Next to it is a Transit Cover for the Igniter Pad that has the instructions that following the use of the Bag Charge that the Transit Cover must be returned to the Depot.
The Igniter bag is made from finely woven wool and it also has woolen ties. The Transit Cover for the Igniter Pad looks to be made of cotton. The Igniter Pad was originally filled with black powder.
It was very hard to find any information at all but in addition to the translations of the labels I managed to find brief mention of them in the following references;
http://www.navweaps.com/Weapons/WNJAP_6-50_t41.htm
6"/50 (15.2 cm) Vickers Mark M
6"/50 (15.2 cm) Mark II and Mark III
15 cm/50 (6") 41st Year Type
The propellant charge was in one bag with a 2.1 oz (60 gm) black powder igniter.
As well the US Technical Mission to Japan report of Feb. 1946 titled Japanese Ammunition Primers states:
The ignition charges for cartridge cases are contained in the brass container forming an integral part of the outside primer body, while in the case of bag guns the ignition charge is in the form of a pad secured to the bag charge. These ignition charges are, in each case, black powder. When ignition charges were secured to bag charges, they used to be contained in a wool bag. It is believed that since 1942, after the supply of wool was cut off, silk was sub­stituted.
The two photos to the left shows the front and reverse of the Igniter Pad and the photo to the right shows the Igniter Pad Transit Cover.
Cheers,
BOUGAINVILLE
