The staff at Jefferson University's JeffDesign Lab are interested in restoring the old Philadelphia Federal Reserve vault door located at 925 Chestnut St. in the basement level. I showed them the see thru Remote Combination Viewer at the One King West Hotel (Toronto) with info placard and they would like to do the same. PM me if you are interested in the work or know someone in the area qualified to do the work, thx.
