The process $eγ\toνb\bar t$ can serve as a unique tool for measuring the $Wtb$ coupling. We show that allowing for realistic luminosity and backgrounds, the size of this coupling can be determined to within 10 (5)\% in an $eγ$ collider built around a 500 (1000) GeV $e^+e^-$ collider.Talk presented at The 2nd International Workshop on Physics and Experiment with Linear $e^+e^-$ Colliders, Waikoloa, Hawaii, 3 pages, latex with epsfig and worldsci, FERMILAB-CONF-93/224, OCIP/C-93-10High Energy Physics - Phenomenologytext
