Looking for some information on a boat

Hey everyone,
First time poster here so apologies if this is the wrong place. I'm looking on any information on a boat that, I presume, is of German origin. Images attached below.

What I've been told/have been able to dig up so far myself is that the boat is of German origin, the person who made it was someone called Nico Meyer (this person seems to be an absolute ghost, cannot find ANYTHING on them even after extensive digging), the boat was apparently made in 1961 and it's equipped with a Johnson engine.
The boat is 6.2m in length and 1.8m in width if that could give any extra relevant context.

I'm primarily interested in whether anyone could possibly give any information on the builder/designer but anything is honestly already a huge help. I'm fairly confident that Nico Meyer is either an alias or not actually the person who built the boat at this point so feel free to correct me if anyone has any other leads.

Thanks in advance!
