Below I've compared the transfer on the leaf-bordered Mariners' Compass with that on a similar Garrison Pottery (Dixon) plaque from Sunderland. Look at the waves in the second detail. The plaques are very clearly printed from different transfer plates. The Dixon version is titled 'Mariner's Compass' and the leaf-bordered plaque 'Mariners' Compass' – note the position of the apostrophe.
I just remembered a jug I have with the Mariners' Arms, and ran downstairs to find it. Unfortunately, we now have a fifth variation of that transfer!
