If you are interested in the architecture and a bit of history I'd start with Kindig's "Thoughts On The Kentucky Rifle In It's Golden Age". Book is a bit dated but IMHO still a damn good resource! Lots of pics of lots of long guns!

"Come, shall we go and kill us venison?
And yet it irks me the poor dappled fools,
Being native burghers of this desert city,
Should in their own confines with forked heads
Have their round haunches gored."
