Thanks for the info and the PM. I'll see about getting some high red shots of her shortly. Aside from some minor use marks, which I think inevitable given she's 140 years old, she's definitely the nicest and certainly most interesting firearms I've come across. Previous owner has her regulated to 100yds on a very light smokeless load and gas checked bullets. I have concerns about the reliability of such a light load in the positively cavernous case of the .500BPE as well as the use of non-patched bullets in the Henry rifling. I'm going to start working up a proper load over the holidays using patched bullets and 3F based on my experiences with a C Sharps 45-90 (45- 2 4/10").
