Old wooden boat

Hello, my name is Johan and i live in Belgium.
I'm new to rc boats, (exept for a 90's Korean Academy rc boat that i conducted once..)but i do have some planes and cars.
I bought an old wooden rc boat locally. I dont no nothing about boats but i liked it looks, old and dusty..
Is there someone who is familiar with these? It is 90 centimeters (35 inches) long and 20 centimeters wide, wood and it has a one channel rudder actuator.
The wiring is fabric insulated.
Here are some pictures.
Thank you.

Any one alive here?
