I´m not sure, but it reminds me of a Swedish mount called Swedemount.
They where made of aluminium.

My limited experience is one that sat on a ZKK 602, 375H&H I bought used.
It clipped the screws after a few shots and vent right in the dust bin, never to be seen again

It might be ok on a lesser recoiling rifle though.
But again...I´m not sure if this is the same mount.

That could very well be correct since the seller is Swedish although the knowledge of aluminum as attachment makes me uninterested.
