Incredible World War One Memorial Bronze Sculpture Sharp Details

Incredible World War One Memorial Bronze Sculpture with Sharp Details including spent shell casings and realistic ground texture.
The cast rifle is a British .303 Enfield Rifle with a Helmet welded to the butt of the rifle. 
The base measures 15 1/2 by 14 inches and the sculpture is 41 inches tall. This sculpture is not stamped by the artist in any location I have been able to locate but it does have some age. The sculpture measures approximately 40-50 pounds. (I have not been able to weigh officially)
This was originally purchased out of an estate sale after being de-access from a museum with 2 other statues made for the Russian WW1 soldiers and American Soldiers.
