I am curious to the M Number of this Thomas Top and if anyone has a picture of a complete one. It is 16 1/4" in Dia. I has THOMAS Incused on one of the ears just below the the unglazed firing rest on the very top. On the Underside I can see two cement rings. Its color is a Motled Mahogany. Any Pictures of this one and an "M" number would be most helpful. A value on a complete one would be most useful also for the cataloging purposes. Thanks in Advance
