Oil Pump Tool used on Dave L 's MSS engine work

 I have been working on Dave L 's  1954 MSS motor bottom half, and thought photos of the oil pump tool  used might be of interest. 

The design is based on the drawing of the factory service tool in the Workshop manual. Geoff Blanthorn made up the tool for my workshop about thirty years ago, and Geoff added threaded holes so that hose connections could be made to be able to do flow testing.  The bolts in the tool are set up that one is used to slightly spread the legs allowing the oil pump to slip in, and the other bolt is tightened to clamp it down onto the body. The tool is used to align the oil pump body when re-assembling. The flow test holes are drilled offset , to align with either an early oil pump like a rigid bike uses, when the pump is inserted from one side, or if you flip the tool over, the longer Venom / Viper/ Thruxton size pumps fit and align with the flow testing holes in the tool.
