I am a Remington 1894 collector so not up on Lefever information. The serial number is 70552, the serial number list I looked at on the internet said 1914 I think it was made later than that. The buttplate on my gun has the ring grooves on it (nito special) and looks original to the gun. I was at the OGCA gun show Saturday and saw a all original Lefever GE 20ga with about 70% case color, steel barrels and the buttplate had straight lines on it. Terry
