Closest I could find for typesetting purposes would be Dooijes Deco Engraved

or Boogaloo (also from Nick Curtis) http://myfonts.us/td-WFECAh

Dina Bedrossian's Table Numbers used in the image might have been inspired by a pre-digital era font called Grock. Compare the numbers to those in Grock, as digitized by D.X. Solo and available on a CD sold with the Dover Book of Art Deco Alphabets -- no separate legitimate download.
