Can anyone tell me what this is....?

Hi


The attached are pictures taken from a tree in our garden - can anyone tell me what it is?

The tree is full of fruit this year - although it does not seem to produce every year for some reason. The pictures attached look like some sort of plum and they do have a hard pip in the middle ..... but I think from memory, that the fruit does get quite a bit larger than this.

I have tasted these and they seem perfectly edible - just curious really.

Any help would be welcome.

Hmmmm, not sure, is it a damson of some sort? Definitely looks plummy/damsony to me. How big/small are the fruits? Its hard to tell from the pic.
