The medallion is English, the pin is American.
Blaydon Manure and Alkali Company is a manufacturer in
Blaydon-on-Tyne, a town in the Northeast of England, on the Tyne just
upriver from Newcastle. A quick Google search reveals this view of
the factory as it was in 1923.
Also this nice photo of employees from 1910.
Also this illustration of the factory, c. 1877.
The pin is American. "B B & B" is for Bailey, Banks & Biddle. From
the late 19th century until its acquisition by Zales in 1962 Bailey,
Banks & Biddle was one of the premier jewelers in America, on a par
with Tiffany & Co.
Here is the brief Wikipedia entry
Bailey & Kitchen, as it was originally known, was founded in
Philadelphia in 1832. It become Bailey & Co. in 1841, and Bailey
Banks & Biddle in 1878.
At the turn of the century, Bailey Banks & Biddle was
commissioned by the U. S. Government to update the Great Seal of
the United States; its design today remains the official version
of the seal. The company also designed and made many of the
military medals that are still used today, including the Medal of
Honor, the Silver Star, the Bronze Star and the Purple Heart.
In 1962, Bailey Banks & Biddle became a part of the Zale
Corporation. Zale opened many Bailey Banks & Biddle stores in
numerous cities. In 2007, Zale Corporation sold the 65-store
jewelry chain to Finlay Enterprises. Finlay Enterprises filed for
Chapter 11 bankruptcy in August 2009, and Bailey Banks & Biddle
was acquired by the current owners in the spring of 2010.

Today's Bailey, Banks & Biddle bears no relation to the venerable
establishment except for the name.
