Some type of ornamental cherry, maybe weeping cherry?What kind of cherry is this? It's not black cherry and I can't find bark like this in my tree book. Western Pennsylvania.

The bark on the small end of the log looks like your picture.View attachment 76028
This piece was given to me on the 22nd of May it was about 5" diameter and about 18" long. The bark looked like what you would see on birch except for the color. The exposed ends were already checked badly so I cut both ends off and proceeded to turn a goblet. The piece in the middle has the dovetail tenon and notice the bark is partially missing on the goblet, but the remaining developed that ripple which I believe is because the wood shrinks more than the bark. The wood looks like typical cherry but the smell as the wood was exposed was different than black cherry.
I agree and since the tree I have was cut locally and it does not look like the bark on any of the naturally occurring varieties in my area it is likely some yard tree, so I am not much help in identifying it.The bark on the small end of the log looks like your picture.
