Why are you looking to swap?
Cylinders, especially on the older revolvers, are hand fit and often as not aren't direct swaps or drop in.
You can try a direct swap, though, but will need to perform all the important function checks and spec measurements. Even then, it may not play well under live fire.
Better bet is to swap all the internals from the old cylinder into the one you're swapping in to have the least likelihood of fit issues, but it isn't guaranteed, either and you still need to perform critical function and spec checks here too.
If it's truly necessary, a qualified revolversmith is your best bet of all.
