Can't say that the manufacturer name rings any bells.
The odor, or lack thereof could be due to the age or usage and/or storage conditions over the years. A close examination of the grain might help you to determine what it is lined with. When doing this, keep in mind that spanish cedar is not the only wood that you can line a humidor with. Mahogany, which is the family from which spanish cedar comes from (yeah, spanish cedar isn't really cedar, it just smells that way), is also perfectly acceptable, possibly even superior, and was somewhat common until it was displaced by it's lower cost cousin, SC.

Other woods have been used in the past too, and there is nothing wrong with them, they just weren't all that common for one reason or the other.
