From the left:
Double exhaust call with 10 and 8 mm straight bore fitted with a Carver toneboard.
Closed reed with 10 mm straight bore fitted with JC double reed (loud)
Then the "Evil twins" two onepiece openreed calls also with a 10mm straight bore.
The 10mm straight bore has proven to build up a good backpressure in the call body and makes really nice loud sound for medium range calling, all calls/callbodies are made out of Moose antler.
Thanks for looking!!
