Thank you all for your replies. Boy do I wish I had just sent it directly to Barbour for reproofing. But the Horse Country folks told me that sending it directly to Barbour would take forever, and if I sent it through them to their person (who required it be "cleaned" first) in Maine, I'd have it back in just a couple weeks...a bit ironic looking back now!
I am working on writing a letter to Marion/Horse Country. I really trusted her with the well-being of my coat, since I considered her and her employee "experts" in the field, and just feel so let down. If that doesn't work out I'll start perusing ebay for a used, less-expensive coat, but it certainly won't be able to replace the sentimental value my current one has.
Again, thanks everyone for your thoughts on the matter!
