Imperial Eastman Annie A-12 Hermetic Unit & Component Analyzer USA made. I got this in a lot at an estate sale. I have no idea how this works, so item is being sold untested. The latch on the case is cracked as shown in  the photos. Item comes with the manual and the Tecumseh manual shown in the photos. ITEM SOLD AS SHOWN AS FOUND PLEASE ASK QUESTIONS AND ASK FOR MORE PHOTOS IF NEEDED THANK YOU.
