Mainca / Fuerpla Sausage Filler Locking Nut Metal - Used
Spares Hubby has gathered over the years, he has had several Mainca Sausage Fillers. It fits his current Filler which I think is a FC-12.
He thinks this one might be a Fuerpla, it fits the Mainca as well.
I have other bits to list.
Used old, still works.
