Few weeks back found these 2 beauties just a few miles from my house. I don't know much about the Hawekotte & Klausmann, but I know it is missing some parts! the Ajax was missing its brushes, so I made a set from some copper sheet. Runs like a treat! If anyone has leads on how or what parts the Hawekotte & Klausmann is missing, that would be greatly appreciated, if not I suspect I just gotta dig around!
