克虜伯75mm野炮 文章參考如下: http://landships.activeboard.com/mobile.spark?p=topic&topic=51281329&page=1 在第一次世界大戰之前，有兩大外銷野炮陣營，一個就是法國75小姐，一個就是德國克虜伯的75野炮( 簡稱克野 ) 這兩家最大的相同處是砲彈的重量，法國是5.5公斤重的榴彈，榴散彈是7.25公斤重，而克野是5.5~6.75公斤；至於其他性能幾乎一致；但是克虜伯公司從M1902/03/05/09/12/1913等等不同的砲型都可以讓客戶挑選式樣，甚至確認砲管長度後才發包生產，身段柔軟導致銷售屢創佳績，連拉丁語系的中南美國家都採用，讓斯奈德很吃味，同其外銷量只有1/10。 根據洋人考據顯示1905~06年在買完72門克式小山砲後清庭發議價單給克虜伯說要買36門野砲與36門山砲，而1907年開始測試對方送來的樣砲，總計有L28/ L29/L30/L31等倍俓炮管長度的野炮於漢陽兵工廠內測試四週，後來根據測試結果L29倍的野炮重量與性能較能兼顧；遂開始了採購之舉，當然漢陽廠也開始在1914仿造M1905野炮，但是重量多了25.5公斤達到967公斤的全炮重。 整個購買的狀況又跟實際上運作不同，根據洋人查的結果: I've just received some information from Herr Herbert Jager on deliveries of 75mm Krupp guns prior to WW1. China - received two types of guns: 7.5cm L/29 (schwer) - 1909: 60; 1912: 72; total 132 7.5cm L/30 - 1904: 36; 1905: 8; 1906: 19; 1911: 5; total 68
話風一轉說到鬼子，日本wiki寫說1907年才決定生產38式野炮若真的是m1903的構型那炮彈重量也應該是6.35公斤重而非5.5公斤，這點可能要靠日本人自己去釐清，因為改良式38野炮採用90式榴彈不含引信重5.71公斤，94式榴彈6.02公斤，90式尖榴彈6.17公斤，也就是說從1925年開始日本就沒在生產5.5公斤的砲彈，目前無法確認10年式榴彈的重量是否是5.5公斤，所以以往看到日本75榴彈比美國75山砲砲彈輕的文章可能有誤。 而根據美軍1944年的戰時文件Japanese Field Artillery中就說38式野炮是仿造M1905 It gives around 1915 as a starting date for the model 38 improvement programm and says elsewhere: "During World War I the Japanese made major modifications in the construction of the Model 38 (1905) 75-mm gun. 41騎兵砲??
接下來就是38野炮的砲尾閉鎖方式: I've read that Argentina held field gun evaluation trials before they ordered the Krupp gun. I suspect the Argentine Army requested that Krupp should modify the standard 75mm. There is a Krupp patent for an interrupted screw breech dating from about 1905 which looks like this breech. The 75mm Krupp Gebrigskanone M1908 (the one for the Japanese) seems to have used the same breech design. It would be nice to know how many guns Argentina purchased and how long they were in service. I have a recollection that some of the 75mm Krupp guns were reworked as a close support gun in the 40s(?)
