Examples of sorted and inventoried tools. Upon identification it was discovered that these tools were highly specialized and potentially one-of-a-kind examples. The left tool was designed to cool large bearings with a cryogenic liquid to aid their removal during overhaul of a BMW 801 engine, like the one used to power the Focke Wulf FW-190. The right tool was designed to be used on the cylinder heads of several different types of Daimler-Benz engines, such as those used to power the He-219 Night Fighter currently being restored at the Paul E. Garber Restoration and Storage Facility.
