I can see I am not very successfull with shotshells either when they are very old US designs or when they are not British.
This last point is very funny because most of the shells sold by British gunmakers in the old days where not made by Kynoch or Eley but by Fiocchi or SFM !!! But this is another story.
Anyway, here is a cutting of an Kynoch shell dated 1896.
Interesting because of the cone base.
PS : Still looking for information about Bland punt gun shells.
