Autumn Colours

We can always count on this tree in our garden to produce some lovely autumn colours. This year it seems to have beaten the rest of the trees around in its advance in turning to autum foliage. I say " this tree" advisedly as unfortunately I can not identify it and would be very grateful if anyone out there can tell us what it is. The trials of being second owners of a property are that you may never know exactly what is planted in your garden.

It is a rhus typhina or stag's horn sumach which hales from North America. Thanks admirers for the identification.
