A new one on me. Any ideas?

[Mr. Bish]

I'm guessing it's a non common ash. It leaves later in the year than other trees (Mid June apparently and looses leaves and the stalk holding them early). Tree is in good health but customers nor I have any idea at all. The leaves are apparently ash shaped in compound pinnate but longer and thinner than the usual ash trees.

The bark is what has thrown me mostly and the shape that the tree is growing.

 

If someone positively identifies this as a mountain ash I will feel mighty embarrassed:blushing:

 

Looking at the profile now it looks very ash like but the bark is just wrong. Please help

Caucasian Ash or White Ash?

Just looking at the bark, Robinia

[son of a birch]

the bark looks... walnut-esque?

[RobArb]

I'd go with slack on this, Bark is very Robinia like and does have pinnate leaves

 

If it was an Ash (which i doubt) I'd go with Fraxinus angustifolia (narrow-leaved ash)

[Neil Frost]

The bark is also very much like Fraxinus Americana.

Raywood Ash? Bark doesn't look typical of ash though but then again there is always the exception!

Bark and shape suggests Catalpa. Leaves would suggest mannor Ash.
