The first two photos were sent to me by the late Billy Pyle some years ago. Pyle had a registered Model 1918A2 from WW2 and enjoyed shooting it at his private range
The first photo showing the unipod is quite a rare photo, also the heavy finned barrel from the 1920's is not common either.
The wood stock is I believe from pre war days and made for the 1918A1 or A2, it was recovered at a military salvage many years ago
