Notes
Charles William Andrews commenced in business at 6 Great Winchester Street in 1882.
In 1891 the firm opened a factory in Birmingham at 13 Bath Street, and became a limited liability company.

In 1901 they occupied 5-6 Great Winchester Street, London, and in 1913 they moved to 2 Bradford Avenue.

In 1914 the Birmingham factory moved to Barton Passage, Newhall Street, but it probably closed in 1915.

The firm appears to have closed in 1917, but may have continued as Andrews Firearms and Accessories Co.
