This is in Bologna Museum and was known to Haeberlin (pl. 52). (Link to English translation of Museum Page). No find locale is listed. No attribution of ‘mint’ is listed. I’m on a plane coming back from Iceland so I can’t check Vecchi 2014 and other likely places… I’m intrigued. Do you know about other aes grave with spues attached?
