UPDATE: After speaking with a representative from the seller they told me that they had accidentally shipped a 'multi national' keyboard. This makes no sense as it has no international markings at all. It looks just like a typical US keyboard.After researching the FRU and other identification on the supplied keyboard I find the same keyboard listed from other sellers (on Amazon and Ebay) as a US keyboard and, more importantly, listed as 'compatible', not 'genuine'. So, I am not convinced it is a Lenovo keyboard for a Thinkpad. Another thing that makes me suspicious is that the trackpoint cap is loose and has a much smaller socket than the caps on other Thinkpad keyboards. So, the trackpoint cap from the keyboard that this was supposed to replace would not fit.After careful examination of the keyboard itself it looks like one corner of the frame (near the ESC key) was supplied bent (or twisted) which could affect key feel and which would stop it being fitted to my laptop. So, I am returning it for a refund.
