Need a Model 617 Barrel

[Big Cholla]

I posted this in "WTB", but it might get more results here; I am building a .22 LR revolver out of a police trade-in Model 65. The only thing remaining that I need is a Model 617 barrel. I want a 4", but will take a 6" if that is all that I am offered. Thanks ............ Big Cholla
