I'm no expert, but a year ago when I was visiting my home town of Williamsburg (less than an hour south east of Richmond), a vintage card shop owner was telling me the factory in Richmond was torn down years and years ago. I do know there are a bunch of apartments/condos in Richmond in old tobacco warehouses and factories, but I don't think they're the ones related to T206.
More info can be found about ALC on this
old Net54 post. It sounds like the company was in NYC and their building still stands - at least as of 2008.
There are many on Net54 with far more knowledge about this subject than me, so hopefully they'll chime in for you. Also, Net54 member Jason Wells lives in Richmond, so he might be able to shed light on my previous statement about the apartments.
