The Obuzierul Krupp, calibrul 105 mm, model 1912 was a Romanian upgrade of the German 10.5 cm Feldhaubitze 98/09 howitzer used extensively during World War I. After two years of planning and experimentation by Romanian officers, the final design was approved and the required modifications were performed at Arsenalul Armatei in Bucharest. The German aiming system was replaced with an improved Romanian system and the maximum range was increased to 6,500 meters, being superior to the 6,300 meters maximum range of its German counterpart. Maximum elevation was also increased from 40° to 60°. Thirty batteries (120 pieces) were converted by Arsenalul Armatei before and during World War I. They appear to have lingered in Romanian service into World War II. Guns captured by the Bulgarians appear to have been placed into service, although they seem to have been out of service by the outbreak of World War II.[1]
