Hancock & Moore set - slight water damage stains

Another rare spotting on H&M. This has been listed for months and no takers. Any thoughts on age, and questions that one should ask?

Hancock and Moore couch and 2 love seats. Retail over $15,000.
Slight water damage stains. Asking $500 total

I can't even begin to guess how old those are. Water damage? Pass.
