Two big ones. 26 cm. Inside as new. Some stone chips in the original SUPRALUX glass. Outer shell and ring are decent. Mounting balls have good threads. These were taken apart some 60 years ago and never assembled .Someone cut the siezed top hinge through instead of drilling out the brass pins and then made the thick brass top plate to join the hinge . Recently cleaned and assembled again . It all fits and does,nt look to bad. Almost looks like " Steam Punk " I have more photos.
