Jim....a GOOGLE search on Kingdon Boilers offers a good number of images of builds......The British Martin Baylis Eng offers them, MacSteam just before closure made a number for sale....Nigel from Pendle Boilers would also be a starting point....[although these are boiler builders & sales people...not for plans]
From my limited understanding, the actual Kingdon boiler construction differed from horizontal water cross tubes to vertical heat tubes?...which would have suited coal burning.....again I am unsure if this carried over to model construction of Kingdon
look a like boilers.....having said this, they are certainly very visually appealing for a model build open launch

KBIO from France is part way with a build and using a Kingdon model boiler...... Another member here,
Bernhard BB has a beautiful open launch + Kingdon build on Youtube.......did your question in Model Engineering offer any results?
Would be interested to hear how you progress........... Derek
