Hi Len
Bob has asked me to answer your query on how to make the cowl vents.
It starts with a length of suitabell dowel and half of one of those balls machines children get sweets out of,you have to search for the size you want and then file a curve on the end of the dowel to match the ball then lay them down together thus
you then superglue them together and when dry fill any gaps with Squadron White Putty ,after thats dry its just sand to the right curveature and paint.The green bits on the tranny’s by the way are covers I made ,as my good lady said the lever ends were quite sharp and my good friend Charlie said the same after a day of sailing,so it was a production line to make them
As you can see its red and green for port and starboard ! She can’t get it wrong then ! can she??
