The 44 does not have FM. FM as we know it today did not start until post WWII. There was some FM in the early 1940s but on a different frequency range than today's stations. Your set has 4 bands. Three shortwave bands (that range from 1.5 to 23 megahertz and one broadcast (known today as AM) band. The schematic info has the ranges for each of the bands. The AM band is selected by turning the wave-band switch fully counter clockwise. ( see the instructions)
Yes you can check the coils by just checking their resistance. Usually something in the range of 10 to 30 ohms. The schematic has the values on it.
Alignment is done with a signal generator that supplies an RF signal with an audio frequency modulating it (usually about 400 Hz). An example (I'm not suggesting you buy this one) that is currently on ebay is seen at this LINK.
