I want to kindly ask you to help me with the identification of this large Klumpatsch. It's about 7.5cm in diameter with a thread diameter of 7cm. The height is about 6.8cm (but there are several mm missing). It has a scale > 60 units. There are some inscriptions that I cannot identify with my humble eyesight. Only letter combination I could identify is FH. It's probably made from zinc (since it's quite heavy - almost 900g), but there are also some brass parts - but the pics might tell you more:



I don't know if the black rubber O-ring running around the bottom is original.
Thanks in advance!
