These are the original Hazet tools that came with an Isetta. The tool roll is a reproduction intended for BMW motorcycles that I picked up on ebay.
A period correct MotoMeter tire pressure gauge to go with the original hazet tools.
Page 28-29 of the Isetta's Owners Manual showing the original tool kit and a picture of an original Bilstein jack from one of my Isetta's.
The tool kit as shown in a 1957 Owners Manual (Export) consisted of a Bilstein jack Model # 312GA, a Gigant (made in Germany) brand screwdriver, a Hazet 22mm x 23mm lug wrench with breaker bar, a set of Hazet combination wrenches in the following sizes; 8mm x 10mm (B15), 9mm x 11mm (B16), 12mm x 14mm (B17), 14mm x 17mm (B18), 19mm x 22mm (B19), and a small unmarked 4 way wrench with 6.5mm, 7mm, 8mm, and 10mm.
