The message
from "Pam Morris" contains these words:

I have almost decided on a Sorbus Vilminorii to plant in the tumble-dryer
drum which now has a feature position in the middle of my newly re-modelled
garden.

But for the past few days I've noticed another tree which I think would look
good, but I've no idea what it is hence this call for help.

The specimen I've seen (whilst driving past) is approx 12 feet in height
with a similar spread. It has lovely (pinnate?) leaf colours just now but
what I find most intriguing is it seems to have upright cones at the end of
each branch.

Can anyone put me out of my misery?

Sounds like sumach, you can check a picture in google/images. Tends to
sucker, hence the spread of the patch you noticed.

Janet.
