Home made action wrench. Made by parting a trash barrel on a 99 action at the stub, capturing the receiver in the barrel vise and then turning the barrel off with a chain wrench and then using the stripped action for a pattern. It mimics a Wilcox Mauser/Springfield wrench with just a milled out slot for the lug. When I have time Ill have milled the other side of the bottom to fit the Enfield No 4 which has a lug that is not square until the bottom but has a radius originating from the receiver tube that tapers towards the lugs bottom which is then finished square. The Enfield lug is also not as wide. The handle is also five inches longer and is knurled for a good grip. Where the bolts pass through the body the holes are oblong which helps center the receiver until the bolts are fully tightened. The idea here is that because there is no inner ring to support to receiver on the inside or a projection on the exterior like the US rifles, it will help prevent oval-ling the receiver on crusty Jap or N04 actions that are hard to separate which have no flat on the bottom for preventing the wrench to slip or apply torque unevenly while under pressure. The previous owner re chambered the barrel to 30'06 and ruined it because the o6 is smaller than 7.7 at the base of the cartridge which = bulge, disqualifying the barrel. There is a milled flat on the 99 action directly behind the lug which somehow must have been used during original assembly.
