Gray Water tank for B-190 Airstream 1997 model

[metch]

I had an unusual (to me anyway) accident which demolished my gray water tank and shroud. The Airstream RV dealer ordered a replacement tank from HQ at Jackson Center. Wrong style received. Was returned.

Now I'm in email communication with Airstream HQ parts department but nothing is resolved at this moment.

I need to buy the tank. The shroud can be built locally using the old one as a pattern.

My QUESTION: Is there a RV salvage place where I might could buy a good used tank? or tank w/shroud? I have photos and measurements of the old one.
