There are 1:72 plans for the Weichmann Type K by George Haddow in Windsock International Vol 22, No 2, March/April 2006, with colour plans of K151 and K167 by Bob Pearson on the back cover. Possibly out of print but an inquiry may be worth trying. K154 appears to have been one of a batch built by Albatros. No picture of that particular machine, but several of some of the others. Hopefully you have some further information; from what the article says, even with that small batch at least 3 different engines were fitted!In passing, looking up this old KuK series by George Haddow reminded me of the extraordinary resource that Windsock was and still is. We really were blessed. Many thanks, Ray Rimell! CheersMark
