Crab apple ID

unfortunately not my tree!!! But I want it....I was too late to the party last year to get some crab apple trees. I want 3 to make a statement across the back of my garden but ideally to be able to use for jams, jellies and also aid in pollination for my other apple trees? 

I spotted a dark leaf one a few years back and I think it may be Harry Baker? But this I spotted this week when I popped to my local food market.
I want it
Any ideas? Could it be Harry Baker? The flowers looked too deep?
