I don't have very many of this particular cab left - I discovered them in a dusty warehouse in Providence in the late 80's. I bought everything I could get my hands on at that time and some did come within the original boxes. They are german glass in nature - this one being an opaque red with a slight green patina. The cab measures 1-1/4 inches across. I used a simple disk with a regular bar pin. I have alot of egyptian items so if your a fan stop by now and then and see what's new.
