What happened to Linnet & Laursen? From just browsing eBay listings, I can see the company survived into the transistor age (mid-60s?) but googling didn't give me much else. I can see they did some funky looking radios way back, and Linnet himself can be seen drilling something in the very early pictures in "From Spark to Icon"...

There were a fair number of Danish radio makers at one point but the dropping of international trade barriers resulted in all but the strongest going out of business.
