I HAVE A RICKMAN(OIL IN THE FRAME)WITHOUT ANY NUMBERS ON THE HEADSTOCK STEERING BLOCK. IT HAS THE BOTTOM OIL FRAME CONN FACING UPWARDS,AND IT HAS AN ODD RADIUSED BRAKET ON THE RIGHT SIDE OF THE FRAME DOWN BY THE SWINGING ARM PLATE.
THE FRAME APPEARS NOT TO HAVE BEEN NICKLEV PLATED. ANY IDEAS WHAT IT IS? ONE IDEA IS THAT IT COULD HAVE BEEN MADE FOR THE POLICE MODEL.
