Your Black Shadow as made in 1998. No idea about production numbers.
Marlin makes one in that chambering.
By the serial number letters BB ahead of your serial number,it sounds to me as if you have a Winchester model 1894 XTR big bore.These were chambered for the .307Win,.356Win,and .375Win,cartridges from 1983-1998.The .375 Win cartridge was only available from 1983-1987.Later they added the 444 Marlin to this line.Being that your rifle is marked with the XTR marking,this dates your rifle from 1983-1989.
