I hope Freebooter doesn't mind ( much ) if i show here my pride and joy.
Santa Cruz de Mudela, XVIII century.
This one has 28 cms.(11") blade. A bit too large for what is considered an operational piece, but i would say it was its actual purpose. It was found in the ruimns of Castro Marim Castle, just across the river from Spanish Ayamonte. The decoration and the probable motto are practicaly gone.
Mind you, apart from this specimen, the couple others i have are close from junk
.
I will have to buy some more decent ones.
