Swedish Mauser Related Old Postcard Again

Soldiers with 1896 rifles somewhere in Sweden, approximately 100 years ago. The photo is very likely to have been taken at the I20 infantry regiment in the town of Umeå in northern Sweden. The buildings look exactly the same. 

The "A-building" located to the right, also housed famous writer Stieg Larsson during his military service in the 1970s.

Problem is that the drawings were used for several other regiments as well, making identification somewhat troublesome.
