Standard bar flap hinge (Del Boy) will not work as the pivot is too

There are two hing points per hinge.
Distance apart varies.

Harry, I am not sure what you mean. I can certainly make bar flap
hinges work, by attaching blocks of wood to the flap and adjoining
counter, then mounting the hinges on the blocks, raising the pivot
points a minimum of half an inch. That is what I will probably do. What
I can't do is mount the hinges directly on the flap and counter.
