Technical Transmission parts identification help needed

A co-worker gave me these parts today but I don't know what they all are or any idea of a value. I am taking them to the swap meet in November. There are two housings and miscellaneous other parts. One of the housings has three different numbers on it and the other just as one.
Any help with a year and value will be greatly appreciated.

Thanks. Is this stuff worth anything?

 

Probably, but it all depends on condition...and it's kind of hard to tell condition from photos, unless they show all the places that could have problems.

here's an example of one that sold for a buck and a half.

Thanks,
I'll look at them closer but I don't think there are any flaws in either of the cases. I'll try to clean them up this weekend if the bad weather doesn't hit us.
