You'll have to click on the links in my last post to see the pictures, I can't get the pictures to downsize. I did remove the oversized pictures.
Here are more pictures of the Richards Type I conversion repro, showing the breech ring, imbedded firing pin, flat hammer, and rear sight on breech ring. These features are what made the Type I superior to the firing pin in hammer/sight on hammer of the Richards Type 2 transition, or the R-M Type 3.
but it was pricey to produce in the 1870's, so they came out with the Types II-III to make conversions worthwhile and cost effective
The Richards Type I operates like a modern gun, and the sights are much better to use than the sight-in-hammer design. The sight on the breech ring looks better, IMHO. The firing pin is foolproof- a more refined, sturdier design- the hammer is flat, and drops down out of the line of sight, when cocked- much easier to aim the gun.
it's a damned shame that in today's economic times, the same rules apply as in the 1870's- they stopped making the Richards Type I repro, for the same reasons- it's a more costly gun to produce.
I have never seen a Richards Type I repro for sale on gunbroker yet- people hang on to them. The value for this gun going up due to these reasons- they are a superior conversion, and hard to find as of late.
