Okay, as I'm still waiting for the workshop to make some space so I can start working my boat I can't just sit and do nothing
I have been replicating the ID plate. Here's the original one next to the printed copy.
I will make the new plate by screen printing it on a 0.5mm aluminum sheet. It should look exactly the same as the original.
The only thing that I still have to find is the punch press numbers for the serial.
