FWIW, you can get a nice big heavy smooth piece of chromed steel at any Sears store. The Craftsman socket wrenches aren't contoured like a Stevens or a bullet bar, but they are cheap and effective. And should you decide to shift to bottleneck slide, with the slide worn on a digit, you can get a precise fit with a Craftsman.
I had a long affair with a nice Dobro squareneck, but I never got used to that big silver eye staring up at me. Traded it for... something worthless & forgettable. Now of course I wish I had it back.
