I will come clean its a $400 chinese one.Basically a knock off of the scherzer design but with a larger bore.

The bore on the chinese one is 11.5mm
The Scherzer is 10.4mm

I have no idea if I am playing it in the correct pitch in that test, I just tuned the main slide so all the valves were in tune with each other.

I need to give it a proper test and check the tuning.
Its probably in G...
