Thanks lads a local woodworker thinks elm as well-I was about to cut it up for a workbench, but guess elm might be a tad rare nowadays so think I'll take care of it.
My guess is stained Ash. Elm tends to have a curlier grain pattern which is what makes it a bugger to split, that looks too uniform to me.
If you can plane or cut a small piece you can try the sniff test, Elm smells like cat pee whereas Ash has a fresher smell.
that looks right, and, my family hail from the Midlands and were Coopers/Wheelrights/Cartwrights, Ash was used, and still is in Morgan cars so ash is more than likely.
Probably an early Morgan with a lightweight bulkhead out there somewhere
I played under it, slept under it and wrote rude pomes underneath the top, on top of the ones writ by my brother who was born before WW2, it older than me, and I'm 67.
