Does anyone know where the serial number is located on current-production Marlin 1894s (in particular, the 1894C in 357 and 1894CL in 32-20)? Is it on the tang or on the receiver? I'm considering getting one and I'd want to put a tang sight on it. Marlin's catalog & web site say the serial number is on the side of the receiver for the Cowboy models, but they don't say anything about the regular 1894s.
