Looking for this camera

Hi. I am looking for a burnett combo in excellent to mint condition. I am also open to a mint Speed Graphic without the 178mm aero ektar lens. I am having a devil of a time finding any of this in top condition and would greatly appreciate it if anyone saw one for sale recently and could connect me. Many thanks

Speed Graphics were made from 1912 to 1970 in several formats.

The most common of these are the Anniversary Speed Graphic, 1940-1946 and the Pacemaker Speed side rangefinder 1947-1954, top rangefinder 1955-1970.
