Hasn't appeared on ASN yet which is a surprise. If indeed it was C185 G-BLOS, it appears to be the floatplane example I recall sitting on the grass at Popham 35 years ago - landed there on floats for conversion back to wheels (I had latterly thought it was amphibious C180 G-BKMM - but I was quite sure my glimpses of it from the A303 were of floats on grass and not a wheel in sight! A pic of 'LOS on the Air Britain site confirms that to be the case!)
May I add my best wishes for a rapid return to full health for the pilot...
