Hi Folks!
Since you are intending to chat about Imperial knives, I though these related knives would prove of interest! I believe they came from the Imperial Schrade Collection, or sell-off of the factory goods.
The dark horn Sfilato (regular jack) is marked C.Mirando (Father of Michael and Felix I believe). He came to the USA, and helped at the cutlery. His knife is marked Frosolone Italy, on the tang.
The dark horn knife with the “orbital” bolster is marked C.Maselli, who was an associate of the Mirandos.
I cannot read the stamps on the two spotted horn knives. Spotted horn was meant to emulate tortoise, but does so poorly in its worn state.
If anyone can shed some light on the spotted knife names, I’d appreciate the info!
