Was the Walrus suitable for smaller naval powers?

Would the Supermarine Walrus have been a good maritime-patrol aircraft for a smaller country such as Greece?

Yes; related Supermarine amphibians served several smaller or overseas forces and offered a practical patrol and utility capability.

Several smaller or overseas services employed aircraft from the same Supermarine amphibian family. The development line ran through the Seal, Seagull, Walrus, and Sea Otter, with British and Australian service among the examples. The machines offered maritime patrol and utility capability without requiring a large carrier force. Continuing Fleet Air Arm orders also kept Supermarine viable before the Spitfire, linking small maritime-aircraft contracts to the survival of an important aircraft company.
