Help with Forehand and Wadsworth Revolver Identification, Parts, and Ammunition

[FWBreaktop]

I have a Forehand and Wadsworth 32cal. break top (or top break) revolver and need your help. I know the gun is a centerfire. It did not come with grips. The serial number is 27023. It has the "FOREHAND & WADSWORTH, WORCESTER, MASS.USA" along with the 2 patent dates of Dec. 7,1886 and Jan. 11, 1887 on the top of the barrel.

I would like to know exactly which model I have, what piece I am missing that fits into a small hole in the frame and holds the extractor cam to force the extractor up, and what type of ammunition this gun originally used. Would someone please help me in this project?

Ammo is black powder 32 s&w (not long). It was made 1902 or earlier, since that's when the company sold.
