So what if there is a tubeset with the same number on both? What is your opinion now and who kept the ledger of the serialization? Was it T. Kilby, Whitworth, then Armstrong, then Vickers?


Note the same number on both tubes, Kilby, Whitworth?


Note the same number on both tubes, Kilby, Krupp, Sauer?


Matska- He finished it but I have serious reservations that he applied the 209595 number or any similar of the above.

You mentioned recently that L. Bernard sold in tubesets, I believe, so does the same apply here as well as single? What is the difference in sourcing between a tubeset stamped with Whitworth's trademark and consecutive numbers on each tube vs. a tubeset stamped with the Whitworth(or Krupp's 3 Ringe) trademark and the same number on each tube( I have seen several of these)?


Kind Regards,
