As promised, I've dropped this TB off as close as I'm going to get to the Cotswolds -- the outskirts of Worcester. Hopefully someone can take it the last little bit from here.
Might be worth attaching a tag to the TB so that anyone picking it up knows that it's supposed to stay in one particular area (perhaps it had a tag in the past, but it's lost it now). Then hopefully it won't go astray again. Good luck!
