What Year?

[TheRealNeil]

Hello - found this baby on the side of the road with a "FREE" sign on it!  I have a couple questions:

1)  What year was it manufactured? (I tried using the age guide but it wasn't clear to me)
2)  Can I get replacement vents for the bottom (I have the 3 round vents and am missing two of the vent covers)

Sorry - having a hard time attaching these pics.  The forum doesn't like the Google Plus URL.

Great pick up! And you can't beat the price.... congrats! Vents can be replaced. Most Ace or True Value hardware stores carry them in stock, or you can find them easily on the infernets....
