Italian release dates of several Spencer/Hill-Movies

Hello everybody at the budterence.tk forum,

greetings! I'm a german film scholar, who's actually preparing a full-length study about Bud Spencer and Terence Hill.
Therefore, I'm still searching for some of the original release dates of several movies:

1. Io sto con gli ippopotami (??.??.1979)
2. Poliziotti superpiù (??.??.1980)
3. Chi trova un tesoro trova un amico (??.11.1981)
4. Cane e gatto (??.??.1982)
5. Nati con la camicia (??.10.1983)
6. Don Camillo (??.2.1984)
7. Non c'è due senza quattro (??.10.1984)
8. Miami Supercops (??.??.1985)
9. Big Man
10. Lucky Luke
11. Extralarge
12. Virtual Weapon
13. Tre per sempre

Therefore I'd like to ask you for your support: Can anyone help? Maybe you have some italian film encyclopedias available or some old movie magazines? Any support is appreciated! Thank you very much!

Furthermore, I've got two questions:
1. Did Terence Hill originally appear in the film "Little Rita nel west" as Terence Hill or still as Mario Girotti? In fact, he's credited in all versions of the film I've seen (including the italian ones) as Terence Hill, although the film already started on 11.8.1967 and Hill said he changed his name for "Dio perdona ... io no!" (which started 31.10.1967). In "La feldmarescialla" (which started 22.12.1967) however, it seems he definitely re-appeared one more time as Mario Girotti?
2. Does anybody know about the cutter who's credited as "Ashley Daleki" in both "Chi trova un amico trova un tesoro" and "Cane e gatto"? I've read that it's either Eugenio Alabiso or Daniele Alabiso. So what's right? And are they brothers?

Thanks again for your support!
