Which type of Ash tree is this

[Timber Futures]

Been back to work on a large Ash which has dropped a couple of large boughs recently, based near Gloucester UK. Not the european Fraxinus excelsior but definitely in the family, with much larger pinnate leaves. It’s an old tree, probably 100 years judging by the trees planted with it, so it has a few dead branches. Also it’s losing its bark majorly (pictures attached), never seen this before, you can see there is a new layer of bark developing below the outer failing layer. If anyone knows what’s up with it I’d be very grateful, both to know the species and is bark condition a feature. 

 

Many thanks.

That's a decent sized one. They have a good habit of splitting out limbs but they do look nice in the autumn.
