How late 15th to mid 16th century guns were aimed, in historic illustrations

[PClemente]

Hi Michael,
Thank you for the interesting posts and detailed pictures.
I was particularly intrigued by the discussion in regards to the sights on early firearms, and it brought to mind the back-sight on a 16th century wheelock carbine that I obtained years ago. The carbine is 32" long and comprised of an 18.5" barrel, with a sight that sits at the base of the barrel. I believe the carbine is possibly French or German dating to 1580 - 1600. The piece exhibits the wear and tear of long and hard usage, and has undergone some repairs and restoration to the stock. I often wonder what good a sight on such a gun would have provided. See the attached pictures...
Regards,
Paul
