Folks,
As a generalization, none of these were made as poacher's guns. Yes, we do see this written about light take-down arms, but poachers never had the money or standing to commission a gunmaker to produce something of this kind.
If a poacher wanted a short gun, easily hidden he'd saw it down himself.
These were often coach guns, light and easy and short to transport, yet effective if required against highwaymen.
Like I said, this is a generalization.
Must get cracking, hay is drying!
