Hallmarking is an internationally recognised endorsement of purity and quality, which is applied to all of our aircraft at the London Assay Office where the silver is tested to determine its grade. Typically the hallmark is stamped onto the side of the fuselage.
MAKERS OR SPONSORS MARK
This mark indicates the organisation responsible for the production of the aircraft and is unique to that organisation. In our case the letters SV represent the two directors of Diverse Images.
