Hello:

It's not much, but it does answer the question concerning the Selma Powder Works: "Did they ever really open?"

http://chroniclingamerica.loc.gov/lccn/sn88064020/1912-06-20/ed-1/seq-4/#date1=1863&index=3&rows=20&words=powder+Selma&searchType=basic&sequence=0&state=&date2=1922&proxtext=Selma+Powder&y=7&x=12&dateFilterType=yearRange&page=1

Sorry its not more, but tis all I could find.

Regards,
Hoyt Cagle
