Just because they have the information does not mean it is readily available in a form which will answer a question. Parts currently in service is probably something they have regular use for and is easy to access. Figuring out the complete history of a part probably takes quite a bit longer and is not a frequent use. Throw in several parts and I can believe they aren't ready to commit to an answer.
