As soon as I have descent pitures taken and found a way to place them here I will post a few to compare them with each other.
The only model I could compare by now was a 8/8 "Doble Temple" Filarmonica by José Monesrrat Pou with a # 14 slug/blank.
Maybe it has been a quick draw of mine but there are pretty similar slugs/blanks from a Solinger factory.

What is the correct word for the not ready ground blade or the status when they were sold to other companies to be further worked on?
Is it slug or blank or something else?
