Many thanks to what is NORMALLY a very helpful bunch of people!  :^)

Yes, Chris, I'm looking for the 255 807 311H, the chrome one with holes for the
rubber "bumper" strips and plastic corner pieces.  I have those parts already.
I'm also aware of the various places where I can buy a new one.  Just thought
I'd go on a fishing expedition for a good used one anyway . . .  So, a "good
used one" is an oxymoron?  Is that what you all are telling me?

I appreciate the humor, but still wouldn't mind serious responses to my serious
question.  Thanks, Herb Mooney, for your serious consideration.
