Dark jade green colored peking glass. The cab is vintage cira 40-50's ( I believe ) - I set them on brand new findings. They measure 2 1/4" long. I believe that the Germans started making these glass pieces in the early 1900's. These cabs could be much older than I think. I found them in an old warehouse in RI many years ago. I'm pretty stingy about useing them hoarder that I am.
