Depends whether you want to assemble a display worthy example or just a vintage anything to operate. I do not understand your point about the 19 Mk 2. That is not a scarce radio at all. 

You can find hacked up radios all day every day. The WS18 COULD be made into something but it would be a long and diligent watch for bits  surfacing in Europe. I just don't like hacked radios. 

I have a hacked PRC-5 and it just breaks my heart to think about all the "improvements" done on it. I need to decide whether trying to reverse those is something i want to take on.
