Original ipod touch restore failing error (400)

Hello,

I have an original ipod touch, which has some sentimental value for my son. He is 10 and forgot his passcode so we have to restore it.

iTunes recognises the device. I click 'restore and update' then agree to Software Update notice and terms.
Then the update fails saying "There was a problem downloading the software for the iPod "iPod". An unknown error occurred (400). "

I have tried multiple computers, and restored other iPods okay. Eventually after many hours with Apple support I looked into network traffic from my PC and discovered the error is because the download is failing, its a server error message. The response from the apple server was HTTP 400 Bad Request

An iPod thats literally year or so younger still works just fine here is the equivalent request has 200 OK

So I think this is a problem that the restore file required for the original ipod touch device is no longer downloadable. Anyone have any suggestions? Seems like I am out of luck.

Thanks in advance for any suggestions

iPod touch, iOS 2.x

For those interested. The URL that fails to download for the original ipod touch is

h t t p : / / pfd.apple.com/ProtectedAsset/iPod/061-5862.2009127.f2dke/iPod1,1_2.2.1_5H11_Res tore.ipsw?downloadKey=<key changes each time>

Returning error HTTP/1.0 400 Bad Request

When restoring another iPod which is slightly newer the URL is

h t t p : / / appldnld.apple.com/iPod/SBML/osx/bundles/041-1920.20111004.CpeEw/iPod_1.2_36B10 147.ipsw.signature

Returning success HTTP/1.1 200 OK
