Very strange oven, Mads. The usable heating space is not very much. That transformer looks very interesting. I wonder if it has more iron in its core than a modern MOT?

Its funny how various international companies are perceived differently in different countries. I have been riding motorcycles for 50 years. Back in the 1960s and 1970s, most people here in the USA thought of Husqvarna as a company that made off-road motorcycles for motocross. That was the perception here in the USA then but even today I think "dirt bikes" when I hear "Husqvarna". From your posting it sounds like Husqvarna is perceived primarily as a weapons company in Denmark. Of coarse I now know that Husqvarna makes many different products but I never knew that they made a microwave oven.

It is a very old Swedish state owned company, from 1689 they make riffles and kept doing so for 300 years. Closed down in 1989.

But among weapons, they also did kitchen appliances, bicycles, motorcycles and power tools.

Their history in brief: http://www.husqvarnagroup.com/en/history-timeline#!/p/215

The C-core transformers are rated for full operation at given current, not like today's undersized MOTs with aluminium wires. I also took apart a Husqvarna model 106 industrial kitchen microwave oven and it had a 4 kVA C-core transformer that weighed 14 kg. You can see that here:

Until this thread came along, Husqvarna made me think of chainsaws. 
A very respectable brand, in a class with the one in this funny commercial (skip to 0:20).

After we had to scrap my wife's old Peugeot automobile, I got her a Peugeot peppermill.

The two rectangular wire rectangles are probably skeleton slots (similar to stripline slots with most of the extra material removed
These are resonant circuits and probably aid evening out the field in the dome
would be interested in the dimensions and i'll try to calculate the res feq
