Garibaldi, this seems to be brass with the same old patina of many of your colonial finds. If it has wood runing it's full length it could possibly be the male end fitting to a fishing rod (although if this is of the age it appears to be, I don't know if there were break apart fishing rods then)
What's interesting is that when you calculate the diameter (against the quarter) it seems to be roughly 54 caliber, a size of some colonial muskets. I don't know if musket ramrods were ever fitted with brass tubular furrules but I assume some were. I do know that some large caliber pistol ramrods were fitted with tubular brass.
