Robert I just acquired a scientific Slide Rule 63 R with case and manual. I have not powered it up yet. This one is one the three or more models Rockwell made. It is idenfified by noting theat the CE key in the upper left is black, the EE and F keuys on that row are orange and the right hand rows from STO and MC down are black. all numbers and . and pi are brown as are the +/- and ARC on the top row. I will power it up to see if it is operational. (No doubt the batters is aged beyond end of life) Regards Dick Lawrence
