Pig three here (brownstoner). Did not know you were a mission fan. I recently salvaged some beams from a building on White st. in Manhattan that I intend to use for stair treads. Mostly Doug fir. I did however also take what appears to be roughly 200 year old oak beams. I'll check the measurements again, but from what I remember - 2 1/2" or 3" x 12" or 14" x 5', 7' & 8'. Mission restoration dream. Let me know if you have any interest. go67racing@mac.com.
