Identify studio pottery glazed bowl AA or AM mark

Hi I have this lovely bowl marked AA or possibly AM ( .maybe for archie mccall)

Many thanks

Does the pot feel heavy for it's size? It's an incised mark, and most professional studio potters in the UK follow the Leach tradition of using a stamped mark, so it might be a hobby potter

Yes it very heavy for its size

Then I'm afraid it's probably by a student or hobbyist
