Made in Kennewick, Washington State by a single proprietor. Excellent scanner but no source for repair or parts. Owner died last July taking the Bluetail line of scanners with him. Probably no more than a couple of dozen were made. If you want to sell it you can probably find a buyer here.
a forum for owners and users of BlueTail scanner receivers, providing firmware, software, and support for all BlueTail products
bluetailscanners.forumotion.com
I have less than a hundred members on the forum, and that covers all the Bluetail scanner models, so I would estimate that there is no more than 500 units total across all models
