I have seen the old DHART helicopter paint around.  It is over at http://www.hovercontrol.com (http://64.34.169.161/cgi-bin/ifolio/imageFolio.cgi?search=DHART&cat=&bool=and).&...; They updated their paint scheme slightly adjusting the name painted diagnally.  The picture you have is the older one (Air instead of Advanced).  The model for the EC-135 is by Heiko Richter.  It can be downloaded from http://www.avsim.com under the file name hrec135.zip.  If you need anything else, please let me know.
