Large tree, compound leaves

Hi all, I'm hoping someone can ID this tree for me. It is quite large (over 50 feet easily), and has compound, jagged leaves. Several pictures of the leaves and of a branch are attached.

Thanks

 

Looks generally like a Caucasian ash. Cultivars have turned rich colors down here but this may a nondescript seedling form that doesn't do as much in fall - and does it later.

 

Ditto to Fraxinus angustifolia subsp. oxycarpa, likely the cultivar 'Raywood' (which here at least, is still green). Its propensity to shed broken branches is another obvious character of this cultivar.

 

'Raywood' are very purple here now, so less likely to be that cultivar.

 

Thanks all, very helpful!
