Up for Buy-It-Now are 6 new old replacement stock intake valves, Toledo Steel part number T 509.  This item was obtained from an old service garage and is not a newly remanufactured part.  According to my vintage Toledo Steel Manual, these are used on the following models and years:

1927-1928 Nash...Special Six (7 bearing)
1929 Nash...Special Six 400 Series

   The valves are in brand new, never used condition and are free of any damage.  The stem diameter of the valves is 0.375 and the head diameter is 1.503   Two of the 6 valves have a spot of extremely minor surface rust on the outer edge of the head from 90 plus years of shelf storage.  May or may not need a light polishing up before installation. Other than that, they are still greased from the manufacturer. The original box is in good condition.
