Do you know what year it was made ?? Can you post a pic ?? Is it for dental use ?? I did ex-ray for years in a physicians office !! That was before regulations became so strict !! I learned on a 1950`s model Picker unit !! Next office I worked at it was a 1939 model Keleket !! The machines for Ex-rays on the body are quite large !! Small units would be for a dental office !!
