This name will be noted in all of the 1859 Saint Louis City Directories.
Dimick was probably the best known and prolific of all the secondary St.
Louis riflemakers and his guns stood on their own reputation. He came
from Kentucky to establish the St. Louis Gun Shop at 38 North Main
Street in 1849. From 1849 through 1864, the firm was known as H. E.
Dimick & Co. From 1865 until Mr. Dimick’s death in 1873 the listing was
simply H. E. Dimick. Thus, here is a clue towards dating your guns with
this mark.
There has been a great deal of confusion about the associates in the H.
E. Dimick & Co. plant. Henry Folsom may have been a partner for a few
years; he was at least important enough in the firm to be listed along
with H. E. Dimick in a City Directory.
