Sixpacker,
My 2 cents worth,
lots of old dresser drawer sides were made of popular being nowday the first wood in hardwood classification the dead give away if it has green or purple disfigurements in it.
another wood used was willow, it has a smell of aspirin when sanded plained or cut. but the wood is softer than popular
if its harder than popular it looks simular to ash, mostly used in furnature and the making of baseball bats.... ash is stringy and hard...
another mention you made is gum, while harder than popular but not by much i have used sweet gum, its great with long planks nearly knotless and pretty straight grain but unless stored weighted it will warp quick ftom tempature and humidity..
guessing wood from reclaims is a tough job, dresser carcarcuses were the show wood and all else was secondary most all but the finest furnature makers bought the cheapest wood that served the purpose. so depending where it was built, might give a better clue.
and the wood could differ from drawer to drawer. commonly called whitewood, which could be most any lighter wood including cottonwood.. wood ages in time and darkens its difficult to name that wood from a photo,
a local millworks owner here is my guru,
take a piece to a local wood worker - millworks maybe they can identify it and give you a good deal on more of it,
the local millwrite here will resaw my planks and plain them to dimention for little of nothing,
