Wtb: collet chuck and expanding mandrel

[Gates Custom Calls]

Hey guys I'm looking for a collet chuck and expanding mandrel sets. I know there are several sites that make them but I've invested a ton of money in my call making and need to find someone who might have extra or selling there own at a decent price. I would like it if they were sets with multiple sizes but really need a 5/8 for duck calls. I have a MT1 on my lathe. It doesn't matter how used they are if the price is right. 

If you have or know someone who has something please let me know.

Thanks!!!
