Speaking of which ...
This example is in exhibition in the Portuguese Royal Palace of Vila Viçosa armour collection.
For what it is worth, the text says that it is a XVIII century Spanish (?) portable mortar, with a 73 m/m mouth. Cast in bronze, with a chamber of much narrower section, with a support hook in the lower part. Silex lock a la French. It shot 'case' with multiple projectiles. It was used in ships and parapets.
