I hope this is not off topic, but I found these while cleaning out my grandfather's gunchest. I've determined that the lower left is a RS Lawrence, patented Feb. 1859 from a Sharps rifle (I think), but can't identify the other two. The lower right appears to me to likely be a military sight I've just identified as a Mauser. The upper item appears to be some type of Globe sight that fits into a dovetail, but it may be something totally different. Does anyone recognize any of these?
