Basing 10mm ACW for Black Powder

In a sense, you are both correct. David Brown is indeed the author. However, Reisswitz Press appears to be a Too Fat Lardies venture.   

From the Too Fat Lardies blog:-
The founding of Reisswitz Press will allow us to publish wargames rules which fall outside the traditional scope of Lard but which share our dedication to historical gaming.

I agree but when someone describes a rule set as "a lardie game" that usually brings a bunch of assumptions with it - cards, blinds, heavy on friction, etc which whilst not always strictly true (Chain uses dice not cards for example) is likely to lead to misunderstanding for a game which is 'merely' published by Rich. If Rich was happy for them to be 'lardie games' you'd think he'd publish them under the TFL logo 

BTW I make no aspersions as to superiority or lack thereof of rules published by either, just the dissimilarity

And of course there are also the various incarnations of Johnny Reb and friends and the Lardie game They Couldn't hit an Elephant, which does use cards.
