If you contact the County Historical Society for the county that Louisville is situated in - you'll find your information on the Sievers-Carson Hardware Company.
You may not find much - but if you send an email or call in the middle of the week, when it's not busy - the folks who staff those places are more than helpful.
Companies like that rose and fell like the tide and may have been bought out or simply went out of business - but the City/County Records of that sort of thing are generally extant, if you want to look.
Good Luck!
Vaya,
