Q: 1. The one I got seems to be the same basic part with some differences. The one in the photo says made in Germany and has threaded holes in the side (I'm not sure what that's for) and mine doesn't say where it's made and has the typical small threaded Safety stop screw holes ...(was just interrupted for the obligatory robot check) ... which it didn't come with. So my questions are was mine made in Germany and was it supposed to come with the safety screws?

Q: 2. Will this work with a RRS lever clamp?

Q: 6. Is this Arca Swiss compatible? Will L brackets from KIRK or RRS lock onto base?

A: There are two parts to your question that was submitted on the product page of the FLM QRP-50 Quick Release Plate (B&H# FLCP50). First, you asked if the FLM QRP-50 Quick Release Plate (B&H# FLCP50) is Arca Swiss-compatible. Our response to that is that yes, it is, and so it will fit in most Arca-compatible quick release clamps. Second, you asked if L brackets from Kirk and Really Right Stuff (subsequently referred to as "RRS") lock into the base. . . of something -- presumably of the FLM QRP-50 Quick Release Plate (B&H# FLCP50). No, they do not as this is a plate and not a clamp. However, as of July 2021, all L brackets made by Kirk or RRS that we currently sell follow the Arca standard and thus fit into most Arca-compatible quick release clamps. As such, if you were asking if those will fit into an Arca-compatible clamp then the answer is that they are indeed designed to do so. (There is some variance among manufacturers, however, so not every plate and clamp combination will always work even if they both claim Arca-compatibility.) If you would also like us to recommend a clamp, please contact us by email, chat, or phone and tell us what the clamp will itself be attached to -- such as to a specific of make and model of tripod head.
