I would like to thank every for such a fast response, I went back to our customer and demanded that they supply us with this old version since they called it out.
Again, great forum/friends
Maybe you should consult the people in your company who wrote the contract you are working on....if that is the case. Normally a contract will state what documents the customer will provide. A lot of customers assume that if you bid a contract, you have access to the correct/current technical and engineering data needed to accomplish what you said you were going to do.
