Thanks for the link, Didier. Actually the Flickr account belongs to Keith Midson who is a member of this forum. His last post dates from 2017 and actually links to his Flickr collection site so I guess it's appropriate to mention it here.
His prototype looks indeed very similar to Matthias' machine, but not identical, so it's really interesting. Keith clearly relates it to the HP-17B (look at the prototype section), although there is no picture showing the prototype turned on.

We can also relate this prototype to the HP-17C prototype that is shown here (unfortunately a poor picture) and that has several common points with Keith's proto, so all in all we can associate it to the HP-17B.
