I assume you only have the part shown in the photo’s ? (ie - you don’t have the case ?)
What you have is the platform and movements from a Yale & Towne Triple ‘ L ’ timelock. This model was produced in very large numbers (16,000 - See “American Genius - Nineteenth Century Bank Locks and Time Locks” )
As such the value is only really going to be the value of the movements, if they are in good working order they are going to be worth around $50 each. If they don’t work or require attention the value is going to be lower.
Hope that helps.
