I have a couple unused locks that I want to start planning rifles around, one is an L&R Manton, the other is an unknown English bar/ shotgun type percussion lock. I've perused the forums and various sites, and I'm leaning towards a small bore, mini Lehigh style for the Manton, and a big bore (is .58 really a big bore?) rifle with the latter. Recommendations and suggestions, as well as perhaps some pieces for inspiration would be appreciated, particularly as i think i might do the english one as my first rifle from a blank.
