ALL HAVILAND IS MARKED with an identifying mark on the back. SEND A SAMPLE, PHOTOGRAPH OR COPY of a saucer or plate to Haviland Matching Service Ltd. Copy both sides of your piece and indicate the colors of your pattern. Patterns are identified according to Arlene Schleiger's reference books. Her books have enabled hundreds of patterns to be identified and matched according to "Schleiger number". Once your pattern has been identified, your needs are kept in our computer file. As pieces become available, you will be notified immediately. There is no charge for identifying your pattern and listing your needs with Haviland Matching Service Ltd.
