Hello,
I know this WW1 Austro Hungarian mine in combination with 1kg or 1/2kg charge but in these pictures, the mine is fitted with strange device (looks like a kitchen extractor hood !)
I did not read books about it. Does anyone know what is this strange shape ?
Mine with common 1kg and 1/2kg charge :


Other combo strange combo (??) :
