Attached shots showing the 3-inch and 4.2-inch mortar cleaning rods along with a 3-inch bomb extractor which is used when a bomb is dropped down the barrel and it doesn't launch for some reason.
The cleaning rods are made from what appears to be galvanized 1/2 pipe with an OD of .70" with pipe fittings joining the sections. Handles are 6.5" and the shaft of the 3-inch pattern is 42.5" with an overall length (including pigtail) of 52". The 4.2-inch pattern has an overall length of 64".
The extraction tool is made from solid 3/8" rod. Handle is 9" with the shaft being 39" and an overall length of 40.5". The disc is the inside diameter of the mortar barrel and it ensures that the cup section can only slide straight down and onto the fuze of the bomb. The cup has internal threads identical to the removable safety cover used on a mortar bomb. While being made of steel, a mockup could be made using one of the alloy safety covers.
