Old AAR Signal Cell jar and lid. I have a tape measure beside the jar and the lid to show the dimensions. The jar has small bubbles in the glass as well as what I call waves in the glass. The top has a small crack that is shown in the photos. It is between the second A and the R in the AAR. The reverse side of the lid has a small chip that I believe, caused the crack. Not very bad but definitely there. The top of the jar has a few very small chips. They may not even show up in the photos. All in all I believe a really nice jar. It is being sold as is. Please check out all of the photos.
