This piece of ordnance came as an Andrew dropping. It’s a 3.7cm HE round designed to be fired from the BK-3.7 aircraft cannon as fitted on HS129’s or Ju87-G’s. It was also used in a range of 3.7cm FlaK.18/36/37/43 auto cannons.
The fuse is a 3.7-cm KOPFZUENDER ZERL. PV self destroying timed type. On acceleration the igniferous detonator in the displaced recess sets back on the striker. The flash from the detonator passes through the flash channels to the powder pellet in the radial channel and to the lower end of the delay filling in the first of the vertical channels. When the pellet in the radial channel disintegrates the bolt is thrown out-wards by centrifugal force leaving the striker held off the detonator in the magazine by the creep action resulting from deceleration.
On impact the striker is driven in by the hammer and pierces the detonator in the top of the magazine. During flight, the burning of the delay composition in the first vertical channel is transmitted by the gunpowder in the traverse channel to the delay composition in the second vertical channel. When direct action does not occur before the composition burns to the base of the second channel, the disk of gunpowder confined in the top of the magazine adapter is ignited and explodes and thus initiates the detonation of the magazine.
The fuse was manufactured by BLW, that is Gritzner-Kayser AG in Karlsruhe-Durlach in 1943. The casing is marked as manufactured in 1940 for a Flak 18.
A few weeks ago I bought a sweet No5 Mk1infantry rifle. When I buy these things I try to make sure I get a small amount of period ammunition with them, just in case the urge overtakes me. This ammunition inner is Ball Mark VIIz ammunition loaded with nitrocelluose propellant. Manufactured byDefence Industries, part of Canadian Industries Ltd. The I.G. Canada means Inspector General Canada.
Simple little item, a ten round package of .303 rifle ammunition, intended for the Enfield infantry rifle and similar vintage weapons. This pack of ten is dated 1941 and manufactured by CAC, the Colonial Ammunition Company of New Zealand. This was the first ammunition company established in Australasia.
Shrapnel and shell fragments accounted for a large proportion of those killed and wounded in WW1. Those blown into the ether by high explosive to one side, artillery accounted for around 70% of casualties. These six balls were recovered from the Thiepval Redoubt on the Somme and are German in origin. Thiepval was a slaughterhouse on the first day of the attack and, despite early success, took a savage pounding from German counter-fire.
These two cartons arrived in the mail today, all the way from the U.S. I expect you won’t be that excited by them but finding unopened cartons of wartime Japanese Nambu ammunition is almost unobtainium. Getting them into Canada from the States is a painful experience as any ammunition export from the US requires Department of the Interior approval. These two cartons are marked almost identically. The star marking is for the Tokyo First Arsenal. The first line of characters is “ju-yon-nen-shiki-ken-ju-jip-po” which translates to “Type 14 Handgun Ammunition”. The second row is “ju-go-hatsu” meaning “15 rounds”. On the underneath of the cartons are the stamps for “sho” meaning Showa Year and 19.11, which translates to November 1944. These are perfect for my 1944 Type 14 Pistol
