Question Historical accurate orbital elements

I'm making a scenario for the ATV-4 flight which launched some 30 days ago. For that I need accurate orbital elements for the International Space Station.
I've found several webpages with orbital elements for the ISS, but most of them only contain elements from a day or two ago, and nothing more. I can use the scenario editor and turn the date back to 5th of June, but I fear that it is inaccurate if you take all the perturbations into consideration (atmospheric drag, nonspherical gravity, etc.).

I've searched on both Orbiter-Forum and other places, and CelesTrak has been mentioned. I can find historical parameters for Zarya, but (if I read the TLE values right) only from the end of 1998 to the last days of 2004. Of course, that doesn't help at all.
I moved on, and found day-to-day elements for the ATV-4, but sadly not for the ISS.

Can anybody help me find historical accurate orbital elements for the International Space Station from the 5th of June 2013 2-or-so days?

If I remember correctly, the request function works great, I've already used it for a Soyuz T-15 scenario.

Data is available for all unclassified objects from 1957 through the latest TLE update.
So it should have the data you need.

Thank you, astrosammy.

How long time did it take before you got the elements?

I can't remember, but not longer than a day.

Yeah, I've gotten them now.

It took just over two hours. Thanks for the help again!

Or if you are interested, just sign up an account with NORAD - I successfully did it by filling in my university as the affiliate organization.
