- The first inventory in the Harparskog-line was made in 1942, when the Finnish Defence Forces made the first fortification cards for the structures in Harparskog-line. In 1955 the structures in the defensive line were inspected once again and at that time, description part for the original fortification cards were made. The description from 1955 gives very detailed information about the structures, as there's even a full inventory what should be in the structures and what is missing.

- Notes are based on my own personal observations in the defensive line during the years 2005 & 2006.
