David,
I believe there is, but I am not sure which regiment(s) are based in Saumur. Saumur does house the Cavalry school. Musee des Blindes is the national tank museum and all vehicles and wrecks of interest found in France were moved to Saumur sooner or later. From what I have heard, even some of the vehicles that remained in the Trun scrapyard into the 80's were moved to Saumur.
It seems my description of the number of Panthers in Saumur and their history was not entirely accurate; better to follow the list of surviving panzers
