Robert Hennell 1 large Silver Knife

Hi folks I happen to have a lovely (Micheal Myers) type Robert Hennell 1 table knife I’m currently trying to rub a couple of hundred years of muck, tar kinda stuff and good ol usage marks…wondering if it holds any value?

Thanks in advance people

If there is any silver then there is some value, but probably not a lot. See if you can find something similar in Ebay’s “Sold” listings to get an idea of potential value.
