The vent cover came off and was lost on the way home with my old Scamp
. Luckily only the cover was lost and the aluminum pieces were left so I was able to source what I needed from Scamp
. Scamp said they had no other parts for that model of vent so I assume the only recourses are to find or fabricate new pieces or install a whole new (larger) vent hatch. If it is only the channel you are missing I would take a stab at finding a similiar aluminum channel or even fabricating something out of some hardwood. I was successfully replced metal pieces with easier to make at home wood pieces before. Especially on something low stress and low speed like this.
