1863 remington lock parts

Does the 1863 remington rifle aka zouave share lock parts with any other rifle or musket?

The Zoli/Navy Arms Zouave replicas use the same lock in their Mississippi rifleguns.

If you are talking about an original Zouave... while the lock profile is of the 1841 Mississippi pattern, there are some changes that were made. The tumbler and main spring were adapted to use a link vs the spring bearing directly on the tumbler. Also the main spring screw used to secure the spring to the plate was discarded with. The bridle, sear, and sear spring "might" interchange, not sure as I've never tried. The hammer of the Zouave also has a slightly different profile in the area of the thumb spur but again "might interchange.
The Italians reproduced the Zouave first and I suppose saw no reason to use a different lock for the Mississippi when it went into production later.
