This photograph was likely taken during the 1903 Kaiser's Birthday celebration. The unit is 10 Foot Artillery Regiment Reserve. 15cm. s.F.H 1893 models are seen to either side of the group and one center top. The other smaller pieces are the model 9cm. C/73 Kanone (gun) also produced by Frederick Krupp. The 9cm gun was also a Foot Artillery piece with good mobility but lacked the shell weight and high trajectory fire capability of the s.F.H.
