Vase with impressed AB mark ( not Alan Brough)

Here is a vase with an impressed AB mark which I am unable to identify. Seem to have seen this mark before but it eludes me.
Height:11cm

Alan Brough ?

he seemed to have s number of marks but not come across this one, assuming it is him

Thanks for your comments folks. I did consider Alan Brough but did not want to suggest it.
On the Alan Brough thread on this site there is an item with a similar method of decoration but that has a painted mark on the base. Perhaps if that one has been attributed correctly then this could be by Alan Brough on style alone. The mark is clearly AB and he did use various styles of seals over the years.
