Very well done, only thing I see missing is a good epoxy floor, I did mine and just love it. You can still do it, but might have to diamond cut the concrete to remove any grease, etc.
I have an Emmert Mfg. Co., Waynesboro, PA Tiger No. 40 - 4 inch vise. It weighs a ton. I just started taking it apart to clean and repaint. I haven't seen an Emmert vise on the long thread, are they that rare or just not that good?
