Pritchard seems fairly certainly an engraver’s error, perhaps he was a bit deaf or simply confused by poor handwriting.

Once the rifle is finished it becomes disproportionately expensive to try to correct this sort of error.

I remember being shown a modern hand built muzzle loader. The engraver had misspelled the maker’s first name - I thought it best not to comment on it.

On Pritchett the man and the bullet he invented there is a recent YouTube video on Paper Cartridges which is well worth watching.
