....In shotguns.

One of the most fascinating things about shotguns is learning about the mechanical advancements, patents and successes.

Intellectual light weight Kamala busted for plagiarizing whole sections of her book raises a fair issue. In her case, lifting word for word directly from Wikipedia without attribution.


London had patents and IP that was enforced.

London Guns attribute - Scott Spindle, Purdey underbolt, South gate ejectors, A&d. Individual craftsmen signed their names.
In modern times Kolar has a Beretta lock up, K80 split barrels and Perazzi draws and wedges dt trigger. Benelli action, now copied in Turkey

When is it plagiarism and when is it innovation in shotguns?

Innovation
Perazzi copied Boss but the DT was a game changer.
Rem 32, now k80 was inspired from Damon Petrik but with a lot of other new features.

Shameless Copies
Kemen, Yildiz, Miroku, Ata, Zoli, Salvinelli, Versamax
