I do not have a photo of the key with the cover for this Paddle. I have made several covers over the years. The cover is made of optically clear Plexiglas and it joined together with box end joints.
I use no glue in the construction. The outside dimensions of the cover are approximately 3.8"x4.7"x"2.7" this allows for a 1/8" gap in the inside from the key to the cover. I am still looking for a photo of the cover and this key for the webpage.
