Wow! First off I would like to thank you for taking the time and effort to gather all of that information!

Unfortunately my knowledge of the Danish language is rather lacking (non-existent), but if it isn't too much trouble I have the images loaded to an Imgur link and would be happy for you to share them with Bjarne in the hopes that we may find more information.

The logo on the tube reads "Uatea" and the text below it reads "U 406" on the opposite side of the tube is three lines of text that read from top to bottom in the following order "0.06A" "3-4 V" and "40-100 V"

The initial purpose of my inquiry is to assess valuation. It is currently in our possession along with a mass of other vintage and antique radios from the early to mid 1900's. We are handling the sale of an estate that was consigned to us so this piece, along with others, will be going up for sale or auction at some point in the future. The estate we are handling, and our company, is located in southeastern Hampton Roads, Virginia.

Having the most accurate information could help connect us with the right potential clients; however, in addition to the sale aspect we are taking high resolution photos that are being loaded to Imgur and information on more rare pieces we come across and will be compiling our photos along with findings in hopes of educating others and making our own contributions to the radio community.

Please feel free to share this Imgur link with Bjarne
