My Build number is 01737 and although I don't have a scanned picture as of this moment (can send one later if you like) I can tell you that there is a definate difference between the "7" and the "1". The top of the "7" goes straight back towards the previous number while the "1" has a bit of a sag to it. I will scan the build sticker for you (unfortunately the picure I have is not the greatest).
Hope this helps you
