From the 1970s onwards, the arms of the sponsoring towns were reproduced on a cast aluminium plate made in seven copies: two for each side of the locomotive, two in reserve (in case of theft or damage), one offered to the sponsoring municipality, one for the SNCF archives, and one for the Cité du Train in Mulhouse. After the introduction of the TGV, the use of screen printing adhesives became widespread. All current coats of arms are produced by the Technicentre du Périgord, which reproduces or adapts the coat of arms of the sponsoring town from the Armorial de France.
