Wood ID, looks like oak but is diffuse porous

[JohnPW]

Hello everyone,

I got given a bit of scrap wood, apparently it's from a door or window frame. It's quite heavy, and looks a lot like oak, it's light brown and has prominent rays. But it's diffuse porous whereas oak is ring porous, and it's also finer grained.

End grain, 20mm across:

The grain is straight, ray flecks on radial surface.

This, I think, is oak. 35mm across:

The piece is actually 2 different woods glued together, 65mm across:

Can anyone ID this wood?

Maybe Iroko, same kind of colour as Oak and was often used for doors and windows.

if the sawdust makes you 'sneezy', it's probably Iroko. It could be chestnut of course, which looks alot like oak. I once had a plank included in an order of oak. It was so porous it was virtually spongy.
