I got a kind reply today from the Musée Saint-Raymond:
"Following your request, I inform you that the stele of the site of the Montels (commune of Lasserre, Aveyron) and the statue-menhir of Frescaty (Lacaune, Tarn) are kept at the headquarters of the Société Archeologique du Midi de la France, at the Hôtel d'Assézat, in Toulouse. They were on loan to the Musée Henri Prades de Montpellier Méditerranée Métropole, as part of the exhibition Statues-menhirs, Stone Mirrors of the Neolithic, from October 2022 to March 2023."
Something is not right. This message is just to keep things from messing up down the road
