Dont have a O&K T18A, BUT; I have a 1940 O&K 15PS-MBA, in orginal paint, in good working order with sharp grass mower attached! I believe it is The Oldest surviving Complete running model of its kind today!? Can anyone confirm, does anyone know of an Older Complete & running model? I am interested anyone can supply information? I have the original papers. OK4u2
