I have the other Confederate revolvers. Need this one to fill my collection in. It is important to me to get one with plain cylinder. Best luck with yours!
If you want a Pietta L&R it ain't gonna be cheap. I started with a Cabela's Pietta 1851 Navy a few years ago that I got on a one-day sale for $170. VTI has all the parts you need (plain cylinder, part round/part octagonal barrel).
https://www.vtigunparts.com/store/shopdisplayproducts.asp?id=66&cat=Pietta+1851+NavyThe barrel is $125. The plain cylinder is $95. The load lever will work just fine. You will then have leftover parts to sell.
Check stock on all items.
I went that route because Pietta does not market that gun, even though I think they could sell a boatload of them. Pietta sometimes amazes me with missed opportunities.
Regards,
Jim
