Identify plum tree

Hi there. I'm new to the gardening game so excuse my lack of knowledge and poor understanding of certain terminology.
We moved into our house over a year ago. We have a spindally looking tree in the bottom
Of the garden which produced a decent crop of plums last summer.
It really needs pruning now, as the branches are sagging all over the place with the weight of fruit. This also limits walking to close to it.
I can't seem to upload the pictures right now but I'll try again later to see if anyone can identify the variety and advise on pruning.

 

Hi welcome to the forum

I suspect you will need a photo of the plum fruit as well .
