picture is kinda hard to see because it is small, do not have any ideas what it is but love the color and markings. Would love to carve it!

The darker spots are scab and flyspeck, apple disease (harmless to eat however). Need a bigger photo for ID of the apple.

More likely the spots are sooty blotch.

Even with a good picture, it's likely only possible to guess at the variety of this apple. And for all you know it could very well be a wild tree with no "pedigree". Is it a large tree? Or a dwarfed tree? Does it have a graft union? This would appear as a large knot near the base of the trunk, or a place where the trunk changes thickness suddenly.
I have a mystery tree in my orchard and I took an apple from it to an "expert panel" to identify it. All I came away with was that it "might" be a Jonagold. I obtained the tree from Raintree but it clearly was not a Gold Star that I ordered. It is, however, a delightful apple.

Hi, Thanks for all your answers. I don't know how to make the picture bigger, I barely got the picture posted at all! But I see the point about difficulties in making an ID. Since the darker green flecks are probably a disease, that removes its one distinctive feature--other than that it has not got any pink, yellow or red coloration; and the flesh is quite white.
The tree itself is probably full size, though not as tall as the trees I grew up with; I had to go up the RR embankment a bit to be able to reach the lowest fruit.

Well, it will just stay a mystery apple as so many are around here.

I have another that I've spotted in a local park that was a farm 100 years ago, that reminds me of a winesap--although the apples are very small (lack of water this year?) but flavorful. I think that I will try to sprout its seeds--realizing that I might not get the same plant.

Raee

Apple identification is extremely difficult. Old timers with adequate memory and experience are rare. I'm around 100's of old varieties on a daily basis and I'll never be very good at the art of identifying apples- my physical memory is just inadequate and I can't file specific textures, coloration, shape and aromas very well.

I'm highly opinionated about the apples I like and probably experience a high range of the individual characteristics of fruit and other food while I'm eating it but without a file cabinet kind of memory I'm just not an expert taster.

Roger Way used to be my ID man. I'd ship him ripe apples I wanted identified. He was famous at Cornell for his ability to identify hundreds of old varieties which he became accustomed to while doing decades of breeding work- he was central to the team that developed Jonagold and many others.

Even he was far from infallible, as years of evaluating his identifications have revealed to me several cases of mistaken identity.
