Well you found out wrong. The wheels are not a set. They came from 2 different bikes originally.
The front wheel is from a Husqvarna M/42 Swedish Military Bike from the 40s. The hub is obsolete. You will not find parts for it other than used cause Husqvarna stopped making those Novo front hubs in 1968.
The rear wheel is from a Monark M/105A Swedish Military Bike from the 60s. The rear hub is a Sachs-Torpedo coaster brake and drum brake hub. This hub can be serviced with new parts as they are still available. The wheel was supplied to Monark by Husqvarna for the M/105A.
Everybody claims there bike is an M/42 cause that is the most desirable model when in fact it is not. Most times it is a Monark M/104A or Monark M/105A.
They made the M/42 with old 26 x 1 1/2 x 2 inch (ISO 54-584, also now known as the new mountain bike size of 27.5 x 2.10 inch) rim size, then came the M/104A with 28 x 1 1/2 x 1 1/2 inch (ISO 40-635). They found out on the field that the 28 inch wheels weren't beefy enough, so when they came out with the next model, the M/105A, they reverted back to the original rim size (54-584 ISO). The only difference between the M/104A and M/105A is the rear hubs, wheel size, fenders, fork and frame.
Here is proof:

Some pics of a M/104A that I am currently restoring:

Here is couple images from the horses mouth (the Swedish Army
Notice the bike in the first image (M/42) and the bottom bike in the second image (M/105A). Also the specs are in the second image. This explains why the "wheelset" appears to be a wheelset when, in fact, it is mismatched off 2 different bikes.
I hope this doesn't piss you off, but I didn't want the infamous M/42 lies to be perpetrated on here since I am a collector of these heavy duty machines.
If you are interested in selling the mismatched wheels, let me know, as I could always use some spare parts provided the price is right.
