K15

there was also a K15 built in 1930s location was probably here, also the tower served as an Air control tower during the WW2. this cca coordinates that were around here placed in a book, i doubt i have it 100% exact on milimetres 60.869947, 28.295346. Better to put it as unofficial since i cant see it on older maps.

Additional info

record is right. Destroyed in 1960s, built in 1949 and the hill was a K37. Expect more to come in Southeastern Finland :) This is just a small preview :)
