Identifying Parquet floor wood?

[hihosilver666]

Hello.

I wonder if you can help me.

We would like to take an existing parquet floor into our extension,

and need to buy more matching wood blocks.

The existing floor was laid in the early 60s, I would like to do the work myself but I'm having trouble identifying the species of wood used in the original floor,

Here is a link to some photos I took, the floor is sanded and varnished,

All the pictures are of the same floor, in different lights.

If you double click on the pictures they do get bigger.

Some people have suggeted it's Merbue, but it doesn't have the small yellow flecks.

Thanks for any help you can give.
