Sweden. Collection militärbrev. A large study collection nice mounted on pages of the Mu1 and Mu2 issues, consisting of used military letters 1922–28 with a lot of different field post and town cancellations. These issues were rationed and used only when there was field service traning about three weeks each year. Otherwise invalid to use. Also a rare military unit "Skaraborgs Regemente" stamped coupon (for exchange for a Mu2). Three known according to Facit. Something for the specialist but also for a collector wishing to study these issues and usages. Also some other documentary material. High catalogue value. (45). Fine quality.
