I will have to check mine and see if it is translucent. I had never noticed that but not something I even looked at. Steve (the dark artist) on here did some fantastic research on the Meccano fett and had a run of them for a while. The one I have I acquired from him actually. He may know this off the top of his head if he is still around. Might send a pm to him to see.
