really gets complicated with Remington which graded the Damascus barrels on Model 1894 guns as follows:
A Grade: Two stripe Damascus (Boston and Oxford)
B Grade: Three stripe Damascus (Oxford 4 S.J. and Chain J)
C Grade: Finer Damascus (Etoile and Washington)
D Grade: Very fine Damascus (Chine and Legia)
E Grade: Finest Damascus (Peiper and Ohonon)
