McKelvey, the top one is a Erfurt, made in 1916, if all matching $800-$1000, but it almost looks reblued (if reblued then worth around $500-$600 and I'd be interested...)
The DWM artillery, being mismatched parts is a "shooter" and worth $800-$1000.
It was made in 1917 (at least the top receiver) and "property" marked 1920 in around 1920 so you would know they were gov't property and not stolen (money was tight in germany after WW1)
