Some cases can be unpredictable. When I received these dials from a calendar clock I found that they had been coated with a varnish that had yellowed over many years. This was not apparent from preliminary photos sent for my review. The usual methods of cleaning could not be utilized and neither could the yellowed varnish be removed. It was difficult to match my new paint to the existing color, altered by the added varnish. The uneven application of the aged varnish is visible in the photos taken before restoration. as overflow seen at the edges. Also the difference in color between the original paint and the presently yellowed varnish can be seen at the very edge of the time dial restoration, where some of the varnish was removed in a test. Despite these unusual issues, the dial restorations were successful.
