Hello All: I am working on a project where phase 2 will require a dental x-ray machine. The original set-up used a 1927 G.E. dental x-ray machine. Does anyone have a working unit for sale or know of a source? Please call or email me at: john at tesla-coil.com www.tesla-coil.com John F. Cooper III Laguna Hills, CA 92653 (949) 701-0005 - cell
