I provide this web page to assist those who repair old Westclox clocks. ClockHistory.com is not a parts supplier - please do not ask us for parts. The fine clock parts suppliers listed on my links page will be happy to send you a catalog if you would like to order new glass lenses.
If you know of anyone that sells old Westclox parts, and I will put the information on this web page.
