The 6” Newton Mortar was the standard medium mortar for the British army in World War One from early 1917.
This project is actually very simple. The items needed are; a regular round toothpick, some card stock, thin wire, glue and a little patience.
I glue the tube to the base and let dry. Then I cut the wire and glue it on. I add a dab of glue to the top to get a ridge around the top. Some wire as hand holds.
Hope this helps!
