Continuining this one as well, (got these things all "almost" ready, usually needing proper paint and non-AUish ordanance)
Minelayer Keihässalmi was build after WWII, to replace the lost sister of Ruotsinsalmi, and she was mainly improved variant of the previous class. She was commisioned in the late 50's and served all way up to 1994, when the brand new Hämeenmaa class finaly replaced her. A versitile and well liked vessel served under various roles aside beeing small coastal minelayer during her career. (she had also various armament fits, but only one's ive seen in pictures are the ones with Bofors 40mm//70 mounts and with the AK-230's and Mr-104 FCR.)
