Did the MP-4 kits come with one of those? I bought a complete/new MP-4 kit several years ago and kept most boxes sealed. The boxes are scattered and stacked deeply amidst many dozens of other boxes so, even if one's in there somewhere, finding it will take some time. That's the reason I haven't posted until now. I'm hoping to soon have a room rearranged and the boxes better sorted so I can get to things when I need to.
