I own a very early model, Gregorelli-Uberti 1851 36 cal Navy cap and ball. In those days they were imported by Navy Arms. Anyhow, I have to replace the loading lever, as a small section of the end holding the locking latch broke off. I spoke with a gentleman at VTI gun parts and he was saying that the modern Uberti lever should fit, but MAY require some minor fitting. I tried long and hard to keep things original but over the years, I have had to replace pieces and parts. Looking for some valuable input from anyone who knows anything about these revolvers. Thanks
