OK, here we go again. Serial number 26 was part of the Swiss trials of 1899, was subsequently altered with a production style trigger, rear toggle link and sight and submitted for the British trials in October of 1900. It has a hand stamped/engraved Swiss cross over the chamber, standard 120mm (4.75") barrel, bordered grips, is not GL marked, and the last time I heard it was residing in the MoD Pattern Room. Check it out at Albert's website
British Serial Number 26. This is a very well known and documented serial number with impeccable provenance. Now what?
