   A serial number tag should be on the machine somewhere. Maybe a couple of photos would be enough is there is no tag. Does the machine have a swing boom?

    It has gray market color. I don't know about an extra valve in that model. The extra valve in those models usually ran the swing boom. There is an extra pump and valve used for running the back fill blade. On all of those machines I've inspected, the usual method is to install an electrically operated diverter valve in the swing boom circuit and use that to run the thumb.

    I think i read somewhere that the free valve ran a hammer attachment
