I rarely use my bugle tube and I don't remember exactly which model it is but it is made by Primos and it's thier smaller bugle that they make, but it works good enough for its purpose. My favorite cows cows are the hyper-lip, single and double and beleive it or not I still use the hoochie moma alot and the other call I use most of the time is actually a custom open reed predator call which does a wonderful selection of different pitched cow/calf sounds.
