Could you help me to find a value for two Strand pat. 123 Fresnel spots I own? Both are in very good working condition with barn doors.They have very little outer wear and only need bulbs.They have no cracks and have all of there parts inside and out.The original paint shows little sign of wear except one has a very minor paint scratch.They are from my research , 1957 vintage. Thank you for your time .I am in Toronto Canada. JIM WILSON.
