Smoking Pipe World War I German 1910

This appears to be a German World War I smoking pipe, it has the German Soldier Helment for the lid and on the back is says Ersatz 1910/12-der 7-Comp. 9.Rhn.Inftr Rgt.n.160.Bonn and  list what appears to be alot of last names.  The front says Reseve Erler it has an intricut painting of 4 soldiers and a bar maid pouring beer out of a keg with the number 160 in the middle and the wording Hoth lebe der Parole, and Reservemann Heimal, it is in good condition no chips or repairs just normal aging, I have found similar smoking pipes but not one like this.
