Well, this seems a pretty obscure rifle. Especially compared to the image of "Sharps" with such falling block and oversized hammer attendant. Seems a super advanced rifle conpared with such as the Ruger Number 1 series which a conjure at the 'mass produced' gold standard.
The main learning experience here is its 'off radar' for much use or interest.
Thanks for the reply gentlemen and I've noted that spelling correction, "No "S"!"
Best!
