Starviper - this could be the one made by http://www.astralprime.co.uk/ methinks. Where-ever you have seen this ship (as in the mod you may have seen it in) - if you read the credits - you would have found out whom made the thing, as well as contact details.

If you wish to use the models, maybe you should start to do some research. Find out whom made them, and email the creators directly.

Can you give me a tip where I could find the email-addresses
