Remington Rand Model 1 Typewriter

I have a Remington Rand Model 1 Typewriter with the case. It was purchased from a yard sale and I would just like to know the value of it in its present condition. There is a silver plate with the following number: P126697, located on the device. All of the keys are in excellent condition with all of the letters and numbers clearly visible. The only thing that it is missing is a ribbon. I am unsure if it has a tabulator or no tabulator. Any help would be greatly appreciated. Thank you.
