Just purchased a TC Seneca from a fellow forum member 36 cal unfired and pristine condition with beautiful wood, metal and bore. It has a peep sight which I am not familiar with having never used or owned a peep. Can you guys tell me about it as far as maker and give some advise keep/put factory sights back on. By the way there is a Santa Claus and he is a member of this forum and took really good care of this gun.
