Well guys from a pure mechanical stand point, ALL the Miroku made 1970s B-78s, later browning 1885s Winchester marked 1885s , even the low wall 1885s are th SAME RIFLE.
When Browing changed from the b-78 to 1885 the changes were ONLY the barrel and the stocks.
When Browning began marketing the Miroku Winchester styled guns inder that name, the only thing they added was the upper rear tang ala the Browing BPCR 1885 rifles.
On the low walls they aslos style the action at the rear to look more like the "knuckle" style stock heads on the orgional Winchesters. The breech block, trigger mmechanism ejectors are ALL the same.
