I've got a relatively recent (2 yr old?) Etek here, that lost the actuating pin in the bottomline rail assembly. We have the knob, but there's nothing inside the ASA to push on the tank valve pin.
I'm sure I can gin one up on the lathe in a few minutes, but can anyone post a photo or two, or better yet some measurements? I can reinvent the wheel here if I have to, just hoping to save a bit of noodle time.
