Need a little assistance on this set??

[ripley802]

Hey all. I saw this one a few weeks back, but the seller was asking quite a bit for it. I waited and it ended with no bids. They also had another lot with engines in it. I was looking at that one too but again too much $$ for me. That one ended, and they relisted twice. Well today i received a reply back and got the deal done for both lots and since the seller was only about 40 min away they only charged $10 to ship, and there is quite a bit.

So here is the lot with my questions:

- What is the set?
- Does it look complete?
- Rare?

And here are the engines. I will have a closer look once they arrive but from the pictures they look in decent condition.

Let me know your thoughts on these.. Total including shipping was $75 US. Thanks all.
