May be Ford, but let me post a few things:
0 = 10 gauge
1 = 12 gauge
3 = 14 gauge
4 = 16 gauge
5 = 18 gauge
6 = 20 gauge
7 = 24 gauge
8 = 28 gauge
C 1 = 9.3X82
C 2 =
C 3 = 8X72 Brenneke
C 4 = 8M. - Mod.88
I'll look for others and the calibres may change over time?
Have to get the order?
8.15 X 461/2 Normal
8,1 x 72 Collath
9,3 X 65
9,3 X 72
9,3 x 80
9,3 x 82
11 x 65
Advert showing Collath 1 gauge & 4 gauge in his gauge scheme.
