Tumbledown Farm .9 Acres (give or take an acre or two)

I have an old walk behind, horse drawn plow that I would like to get a new set of wood handles for. Where or who do I contact to purchase some new handles. The plow is pretty much complete but without handles. I have looked on the internet but have not found anything. If you can help me locate someone that has this type of restoration parts I would much appreciate it. Many thanks,
