I could not recognize it nor too could not find it for C. Modé. I believe that is why Marc forwarded the listing to me. Pretty high number for Sir Joseph Whitworth tubes and I was trying to recall if all tubes wore a consecutive number or if some tubesets had the same number or not. Crossedchisels should have the range written on the back of his hand. Like Sauer's 3 Ringe, each tubeset(I don't think single tube) was accompanied by a certificate and was a warranty that accompanied the tubeset in the even of tube failure.
Kind Regards,
