Info on Danish "Jørgen Høyer a/s"

I tried to find some info on the Danish company “Jørgen Høyer a/s” which made various types of ammunition (no SAA). Their NATO factory code was “JHE”.
Unfortunately the web search did not bring anything usefull.

Does anybody here happen to know details on the company, if it still exists and the main question; has anybody ever seen one of their catalogs?

I don’t know if this may help EOD, but it is worth a shot… No catalogue or cartridge photos unfortunately…

Dave, these I had found before but would be looking for more specific data.
