These are a new supply, not vintage.  They are new stock but some have discoloring inside the well from age.  I believe they are paintable.  I am selling the 3 together as a lot.  They measure about 3 3/4" in H x 2 1/4" in W x 1 1/8" in D.  I took 1 out of the bag it was pkg.'d in for better photo's.
