According to https://ngdc.noaa.gov/geomag/calculators/magcalc.shtml the magnetic declination was 7.50° W in 1928 (when the location was first used for gliding). Today it’s about 3.51° E, so meanwhile the compass should indeed indicate ca. 167°/347°.

Could you provide a source (Nachrichten fuer Luftfahrer) for the official renaming of the runway accounting for the change in magnetic declination?
