Something new, no longer blue (purple just doesn't rhyme)

Looks like the postal service did it again. They are changing the ink color on the vending stamps. The old version, shown here has the machine number and the postage printed in purple ink. Recently (don't have the exact date yet) they have changed the machines to use black ink. My sources in Israel (and on E-bay) show that 8 of the machines have been changed to black ink. Another new variety to add to the collection. Keeping up is hard to do...
