Dresser- West Michigan Furniture Co.

I know very little about this dresser.  It belonged to my grandmother, it was manufactured/sold from West Michigan Furniture Company (still has brass tag attached inside top drawer).  It is solid wood, very heavy, very sturdy and is a light olive color.  It stands 50 inches high and about 33 inches wide with five drawers. This is it's original finish and it has all of it's original pull handles, etc.  Drawers slide in and out as if they were almost new. There is one chip in the paint/finish at the bottom, but it is in very good condition other than that.  

Any information would be helpful.  I'm very curious to know approximately what year it was produced, and perhaps what type of wood its made from...because I'm clueless:)

Thank you, Melissa
