The maker would have called it "English 2 Stripe"
Others
‘Oxford’, Lower grade
Hufnagel (
Hufnägeln or Horseshoe Nails),
Damas fer de clous,
Damas Anglais, or lower grade
Damas Crolle, Remington ‘Oxford 2 S.J.’, most American maker’s ‘Good Damascus’, some Belgian ‘London’
BTW: W. Richards marked guns made by J.P. Clabrough were sold in the U.S. The 1886 catalog from John P. Moore’s Sons, New York listed “Clabrough’s Make” W. Richards.
Or is it a W. Richards, Liverpool?
