It is also possible to find this shield on 10 1/2-inch plates, but some believe that these plates were actually made by another company, Sterling China. The list of milestones and dates is the same as on the shield in the Scammell's Lamberton "DESIGN PATENTED " series. The first china produced by Sterling used up the new-old-stock (NOS) Scammell's Lamberton decals.

Following are common and not-so-common back stamps found in the Centenary line. Not Centenary but certainly in the family tree, this was the china that the Centenary design was based on in 1927.

It was made in England one hundred years earlier in 1827 to commemorate the inception of the Baltimore & Ohio Railroad. The "PATENT APPLIED FOR" china was the original 1927 set and came in two variations (that are known) -- the common blue background and the extremely hard to find white background.

Due to its long history and enormous variation, information on Centenary china can be complex and confusing.

The place to start sorting this out is the back stamp.

A back stamp consists of words, possibly a logo, and other codes placed by the manufacturer on the back of each piece of china.

Properly interpreted, back stamps show the history of the piece.Most commentary on Interpace Centenary says that it was made for souvenirs. Interpace also produced the 150th anniversary celebration china in 1977-1978 under the Shenango name. The Shenango China name and assets were acquired by Syracuse China in 1988, whereupon the plant in New Castle, PA was closed. It had a back stamp of 1827-1927, but general consensus is that it was done in 1993. In 1997, a "170th Anniversary Edition" was produced by Syracuse under the Shenango name and features LIMITED EDITION" on the back stamp. Syracuse continues in business today as a subsidiary of Libbey Glass Company. Every big family has its oddballs, and Centenary has more than its share. Below right is a teapot with the "back stamp shield" printed right on the side.But a 1968 run often turns up -- see the T-27 date code at right -- proving that the Interpace china could have been used on the passenger trains (which stopped in 1971 with the inception of Amtrak). It dates to 1977 and was made under the Shenango name, but it was not a regular production piece. A publicity booklet issued by the railroad in the 1930's said, "While the task [of producing this china] was found greater than anyone imagined in advance, it is felt that the final result ...a fitting commemoration of the hundredth anniversary of America's first passenger and freight railroad." Today, over seventy years later, not only does Centenary continue to commemorate the B&O's hundredth anniversary but also the entire history of one of America's great railroads.Click on either image at right for a larger version. Scammell China of Trenton, New Jersey produced Centenary china under the "Scammell's Lamberton" brand [SCM] from 1927 to the outbreak of W. The patent was applied for by Olive Dennis of the B&O on December 7, 1926 and was granted on May 31, 1927.Scammell's Lamberton used the "PATENT APPLIED FOR" back stamp until 1930 when they changed to "DESIGN PATENTED". The shield shown at right appeared on 9-inch plates in the original set and lists eight milestones and dates. The "DESIGN PATENTED" back stamp was first used in 1930-31 with the introduction of several new pieces not included in the original "PATENT APPLIED FOR" set.However, Sterling remains in business, and their website even indicates a "Lamberton" line. Shenango China produced their first run of Centenary after the War, around 1949(? This is the fairly hard-to -find, white-background Shenango.
