In reply to your letter re Sundial purchased from us in June 1924.

There is no doubt the fumes from the Coal Gas have had some effect upon the dial in question. The only thing we can suggest is for you to soak the dial in a bath of paraffin oil for about 24 hours, then rub over gently with a smooth flat piece of pumice stone, this will remove the crust, then with a stiff brush dipped in paraffin oil scrub well, this should remove the dirt & crust formed in the engraved parts of dial, having developed the engraving to its original form, clean whole of dial with hot soapy water. We would then advise a thin coat of oil being rubbed over dial occasionally to prevent further attacks from the fumes.

Trusting you will find this method satisfactory.
Yours faithfully
