The instrument is made of what appears to be aluminum or stainless steel and is in in excellent condition. The syringe measures about 14 inches long x 3.5 inches wide. The box is complete and a bit tattered -- primarily at the seams. It sports 2 detailed labels as pictured. An unusual and rarely found dental tool of the trade.
This instrument is called a BURTONS VITALOMETER, and was used to measure the health of the tooth pulp.
The case measures 12" tall x 8.5" across x 4.25" deep and is in very good condition. This attractive cabinet sports a 6", circular, front window and comes with all the parts and electrical components as seen in the photos. I have not verified whether this tool functions, but was told that all of the dental instruments were still in use up until the time of the previous owner's retirement.
A unique, visually interesting, piece to add to one's dental collection!
