This new-like balance wheel escapement platform is used on Kieninger-Howard Miller movements, SEW01, AEL series and others. It comes with a plastic cover. It was recently cleaned, lubricated and tested. Please note that platforms work well only when the movement is in good running order. Remove paper shipping tab securing the balance wheel before use. Width .830", Length 1.353", Height .430", length from bottom of platform to bottom pivot .405", overall height .842". The platform is guaranteed against faulty material and workmanship for 1 year.
This is a great replacement unit or one for your next clock building project. Please note that clock platforms are precision and delicate mechanisms. Experience and proper tools are required to successfully install and adjust them, and I'm available to assist. l'm looking forward to your feed back.
