Bill, I think you are referring to the earlier version J. Roberts. They are usually available on E-bay or at your local swap meet. Handle, and two types of B/C, upright and inverted. Somewhat like the current item sold by Brodak. Handle us is normaly not interchangeable with current Brodak offering. Handle of early model is marked with "J. Roberts' only. B/C's were packaged in blue print boxes (upright) and (red) inverted models and they are smaller and thinner than current. Hope this might help.
