In fact EM ALEMANHA sounds very Portuguese; despite such wording doesn't frequently appear, it does show up now and then.
Hoever the letterings on the other face, which 'regularly' show the name of the (German) smith, or words like ESPADEIRO DEL REY, don't match with any word at all, even considering the usual misspellings.
Nothing close to those letterings appear as smith names in Viterbo's work or old exhibition catalogues.
The closest approach to EMFLENTE would be 'Em Frente' (sort of straight ahead), but unlikely, though.
You've got a riddle there; apparently not so easy to crack.
