75mm German WW1 case

[Burney Davis]

I have attached pictures below of a 75 x 277 R 90mm case which I have listed as being for a German field gun. The same type case also appears with Austrian Berndorf markings. My question is what projectiles were used with this case? The only references I can find refer to the mountain gun projectiles and cases in 75mm.

Any help appreciated.

They are not really german - just manufactured in Germany, but not regulary used by the german army (some captured examples became improvised AA guns during WW1). They where used in several Krupp and also Schneider field guns by many different countries. The projectiles used depend on the country where they were used. Some countries used the unchanged Krupp design like the Netherlands, Sweden, Romania. Other countries like Italy, Denmark developed also own ammunition or Belgium and Bulgaria used both Krupp and Schneider designed ammunition. It's easier to count the countries which did NOT use this ammunition than listing the countries which used guns for this ammunition

The primer of your case doesn't look familar to me - it could be a chance to identify the country where it was used.

this drawing of the ammunition of the dutch M.1905 field gun best resembles the original Krupp design of HE and shrapnel shell. The dutch ammunition was imported from Krupp. Later at least cases where made in the Netherlands I think.
