Mystery Part

[SprinTango]

I recently purchased a Plus 2 that came with with several boxes of new and used spares. I have been able to identify everything except the one item in the photos attached. It has a part number tag with something like E026A0002, though the last 0 could be a 6? I don't think it is related to my 1973 plus 2, but don't recognise it as an Elan part either. Suggestions or definite answers much appreciated!

Great, that was quick!
That makes sense, the original 5 speed box was supplied with the car, but it's currently fitted with a 4 speed.
Thanks,
