Another German manufacturer! Here's a Melker monkey wrench dating from, at a guess, 1900-1920ish... There are a few for sale online but no company info online that I can find.
Messerschmitt Kabinenroller on route to 3 speed records for sub-250 three wheelers. The modified 200 cc Sachs motor powered this machine to a blistering speed of 65.75 mph over 1000 miles, 65.24 over 2000 km and 64.03 for 24 hours. The driver's name is not mentioned.
This is a "Gee Dee" German-made "multi-tool" - in all its glory - the handle is hollow. The head of the hammer unscrews from the handle, and those "bits" are stored inside the handle. Clearly a quality tool set for the professional.
Monsieur Bugatti (center, behind steering wheel) with staff and friends posing at Molsheim in 1930. I wonder what the chassis number is. Bugatti register.
