We sent a Midshipman Third Class on a hunt for the stock number of the bubble in the inclinometer on the bulkhead of the Engineering Central Control Station compartment.
Those Metrinch sockets look interesting. I have a set of metric and SAE sockets. I also have a set of metric and SAE wrenches, or spanners as some would call them.
Two places you can find the Milwaukee adjustable wrenches with the metric scale on one side and the inch scale on the other side are Home Depot and Amazon. Probably could find them where ever Milwaukee brand hand tools are sold.
