Sweden. Collection militärbrev. A large study collection nice mounted on pages of the M4, M5, M6 and M7 issues, consisting of both unused and used military letters, unused and used reply stamps on and off covers. A huge lot of varieties, shades and usages. Mainly all that exist according to catalogue. Also notations on pages of "varieties" in the printing that is not mentioned in the catalogues. We have seen about 276 of M4+M5, 111 M6 including typing of all the 24 types of M6, and about 67 M7. Something for the specialist but also for a collector wishing to study this issues. Also some other documentary material. High catalogue value. Please inspect! (454). Fine quality.
