Hello! I'm sorry for posting in english!
I stumbled across this site by accident so I am also sorry for this necropost, but I think this may be on interrest.
I collect and study Swedish army bikes and I was interrested to learn that Estonia used Wiklund bikes!
At the time of the Estonian Wiklunds, the Swedish army was using the M/30. Actually the m/30 was a great number of different bikes bought from all large manufacturers in sweden and they differ wildly. The manufacturers were allowed to sell models from their current catalogue, which changed over the 12 years of the m/30 until it was replaced by the m/42.
In among these were Wiklunds.
I have one of these Wiklunds, which may be of interrest for the forum.
It is not an identical model to the estonian one, primarilly it has a different saddle and different mudguards. Furthermore, the Estonian Wiklunds seem to have been chromed while this one originally was all blued (yes blued steel, like on weapons!)
The rims are, like on the Estonian bicycles, 622 or 28 x 1 5/8, which is a very rare dimension in Sweden. They accept ordinary wired on tyres but it looks like they may also work with beaded (vulst as you and we say) tyres.
The front light, tool box and rack were separately issued with every bike and is not model specific.
To me it seems the frame, bell (!), wheels & crank parts may be the same as on the Estonian Wiklund and the handle bar just missing the fixture for the spoon brake. Spoon brakes were rarely used in sweden after around 1920 and I have never seen one on an m/30

Here you can see the saddle post which shows the blued original finish. All of the bike barring the spokes are blued like this including the bell and the saddle.
Sadly, the m/30 is extremely rare these days and I do not believe I have ever seen the exact same model twice, so finding another one is probably almost impossible..
Just to illustrate, here is another m/30 from the bicycle instruction from 1943. It is a Wiklund, but it seems to be a completely different one! (the illustration is intended to show how a mortar tube could be carried on a bicycle, if you are curious)
