The number 44 on the hub is the year of manufacturing, not number of spokes which is almost always 36 on swedish standard vintage bikes. Normally, bikes are from the same year as the hub or the year after, however, the Fichtel & Sachs-factory was bombed in 1944, so production was stopped. This forced some bike makers to use older but unused hubs from stock. So the bike might be a couple of years younger. The saddle and handles are not original, the back reflector has been repaired with faulty glass and the front lamp is way older than the bike, otherwise pretty neat.
