Todd (nolemmings)That TSN backs may be the 2nd most common back for m101-4, but they are not for m101-5. I was hoping that, as a type collector, you'd happened across a m101-5 with a TSN back. I still have not seen one. I'm not the eyes and ears of the hobby, and only took up m101-5 about a year and a half ago, but I find it odd that nobody seems to have one. Assuming they exist, I would have to say that they are rather scarce, as I have seen all other backs (other than Holmes to Holmes, which you have) on Ebay during that time.
I know this is not exactly the riddle of the Sphynx, but it has bugged me for awhile. May your travels lead you to finding one and posting it here!!!
