I'm new to mechanics and Z's and learning as I go: I have an oil leak on my 7/70 240z, so I removed the oil pump and dropped the oil pan. Laying in the front of the pan was this metal tube and I cannot find it's source. I think it's hollow and has two very small holes along it's shaft; and one end looks like it was brazed. I think it's use is for spraying oil? Is it part of the windage tray? Thank you.

Take off the valve cover and check the spray bar.  I think that your guess is correct.  Hopefully there are no damaged cam lobes.  Also possible that it is left over from some past catastrophe up top.

It is one of the ends of the spray bar, as zedhead said take off the valve cover. Lucky it did not get caught in the timing chain on its way down to the oil pan. 

Yes, that's it! It's on the spray bar by the timing chain, and the cam looks ok. Do I take apart the bar and fit it back in? Or get a new spray bar? Thanks again.

It would need to be brazed back together after taking things apart.  You might find an aftermarket solution.  I did a quick internet look but didn't find anything.

You definitely need to fix it though.  Check your cam shaft carefully.  If it's been that way for long then your cam lobes have not been getting lubrication.  If your cam shaft is shot then you'll want to get an internally oiled camshaft to replace it.

Pictures might help

I purchased one from yoesheadporting.com   It is a very well made aftermarket part. It has been working great for me.

That seems to be the one currently...
