Google image doesnt have a whole lot of GOOD examples of Sika taxidermy work. Hoping some of you can share yours. Thinking about doing a turn/bugle type mount. But may just go with a pedistal or turn.

there are very limited forms on the market for sika unfortunately. Joe Coombs Classics has a pedestal open mouth with a turn similar like you described. It will require a big neck cape in the 20 inch range though. Any form however can be altered into what you want. It only depends on what you want to spend on the mount.
