This looks like a Cushcraft R5 or R7 vertical - a very good piece of kit. Once you get it cleaned up and check that the traps are in good working order you'll have a great DX hunting antenna.
Do a Google search and you'll find several sites on how to refurbish and rebuild the traps.
I have the R6000 a similar Cushcraft antenna that I refurbished last year. Have a look at my website at:
http://ve3mpg.blogspot.com/ - there's an entry on what I used and how it was refurbished. The traps on your antenna are slightly different but there's lots of info on the net to repair these.
The Cushcraft website has downloadable PDF manuals available that will give you all the correct measurements of each element as well as a complete parts list. I used stainless hardware to refurbish my R6000.
