When Navy Arms first offered these... You paid $100 subscription ( Get on the waiting list )
I ordered one ( as did a friend) from Val's daughter, I met her at a Florida Gun Show.
Sometime later I got a Letter from Navy Arms, My gun was ready to ship, please send the final payment of $250.
My friend was a bit strapped for cash by then, so I bought him out and sent for both.
For $350 each I owned two Cavalry Models.
I don't remember exactly when, it was some in the mid to late 80's.
I do recalled the were Pietta's and fit and finish was much better than Pietta standard offerings in other Cap & Ball revolvers.
as to the issues:
pro ...they were very well made, and unique, very nice bluing & no machine marks , Well fitted with walnut checkered Grips. High Quality
con... Hammer springs was almost two thumb heavy and a little awkward (and a stretch for my hands to thumb one handed)
The lever that locks the barrel ( Cav. Model only ) would work loose and allow the barrel to turn.
Army and Navy models don't have this draw back.
Lastly the ramrod for the the Shotgun was a slip fit in the pistol rammer, these would loosen under recoil and slip out ( I lost one , had to make a new one ) a slight bend to the rod, solved that problem.
If you get one get the Army or Navy model ( not the Cav. Mod. because of the reason above ) .
Also they seem to run about twice the cost I paid 18+ years ago ... but heck what doesn't ?
