The B78 was the original design and first patent of JM Browning. Made from 1878 to 1883.
Recent calibers manufactured include 22-250, 243 Winchester, 6mm Remington, 25-06 Remington, 7mm Mag, 30-06 & 45-70.
Only 671 243 Winchesters were made.
No offence but are you sure those years are correct? We are talking about the model 1885.
The B78 also has a different trigger mechanism than the original 1885.
