2nd could both singles and doubles be found in the same serialization?
What do you mean by that, Raimey?
The Whitworth numbering system has always been one number per tube,and in a consecutive order. Of course, those were most often chopper lumps and if one was going to screw up one tube, one would need the proper side to replace it with.
The Purdey tube numbers are marked on each side of the forend loop. The Mode tubes are marked on the tubes themselves and with a very different font.
One is left to wonder who exactly was marking the tubes. My guess is the gun finisher.
I have a 1901 .303 Purdey double and the tube numbers are totally different (14xx) and are not in order compared to the shotgun tubes of the era. The marking is the same in font, location and size, though.
As for your first question, I have never seen this address associated with C.Mode before.
Best regards,
