MacBook keyboard layout does not mach model number!

I'm certain, I have now established that the keyboard in the photograph on the link you gave is the version 1 keyboard and the one that I have is the version 2. The only difference I can see is that the return key spans two rows on the version 2 and 1 row on the version 1.

Many thanks for your concise answer, I feel more confident in just going out and buying a top now that I know hy are interchangeable.

Truth to be said, your topcase may be a V1 or a V2 version. The keyboard in the photo is the V3. This, ordering them by date of production.

v1: Original topcases, volume keys on F4 and F5, orange flex cable, thin plastic, a bit more uniform looking, but frail. Used on the original Core Duo.

v2: The topcases that came out after the "cracking palmrest issue". Like the v1, only often shipped with a grey foxconn flex cable, and a sturdier, more thick plastic, but still fit quite flush on every single A1181

v3: Santa Rosa/Penryn Topcases. Volume Keyboard on F11 and F12, iTunes controls, shipped with the last Macbook before the line was phased out.

If you're a purist, you can get the one that looks exactly like the one you got, otherwise you can choose between the v2 and the v3.

If you've the occasion, you could get the iFixit keyboard: I've got in office an external Apple USB keyboard, and the iTunes keys are useful if you work while listening to music. Otherwise, the choice is yours.

Well, about the return key, be careful!

The iFixit keyboard there has a US layout. Check better if you want a localized layout... for example I had to search for an Italian layout because I needed the accented letters.

So, check beforehand if you need a localized layout, every country may have different special letters. If the picture truly satisfies you, go for it.
