Mini ango sold, Hayden duet still available.
Thanks for diverse inquiries, advice, humorous private messages (some of which really needed to be private!), etc. Contribution sent to site manager, and new owner of anglo seems happy - and can play it much better than I ever could. Good all around.
I may be moving house in a month or so, and would be packing the duet away into climate-controlled storage. If anyone's seriously interested, please PM in the next week or two.
Thanks again to all!
