Servus,

Can anyone tell me wha tthis is?

In wehige Seekunden ist die Anhoehe erreicht und mit einem "Affenzahn" die Kuppe ueberschritten.

Thanks in advance for your help.

Regards,

Helmut

Affenzahn (literally "monkey's tooth" - don't ask me where this expression comes from) means high speed....
Reached the hill within a few seconds and passed the summit with high speed

Its slang and the meaning is "with very high velocity"; it is even today a phrase used in colloquial German
