I have strightened them with a wet rag and water. let it stay wet for the day,strighten it and put between two books or something that want let it move till dry.that should do it.
you couls take something like a paper towel roll and cut length ways ,wet the beard and then roll the tub around it real tight and leav for a few days.that way you don't have to lay the mount down or sideways.
it probablly got damp and bent when the taxidermist was waiting on the form or something and when it dried thats the way it stayed.
good luck and congrats.
Pic's. please
