Hello! Your operator here looks to be a match for our 39-239B. Look it over and let me know what you think!
Sure! Part A seems to be the handle. That would be our 39-114L, though we also sell the 39-451 if you'd like a cover, too.
Part B appears to match our 38-105 lock keeper.
Lastly, for Part C, see our 39-536.
