Just to conclude, my gun is serial #312177 marked S20
I think 1919?
Has ejectors and although the 26" barrels are Marked 0 on the right flat and 4 on the left the bore gauge has them at Mod and Full.
Other barrel markings are "SMOKELESS POWDER STEEL" on right top and "MADE in USA" top left. there is a G on the barrel flat and "nitro proof" in a semi circle on bottom of the front barrel lug and a S on the rear face of the rear locking lug.
I can't wait to get her cleaned up and on the quail in late winter.
Thanks all
