muhle shaving Rocca question

How do I figure out what generation a Rocca is? Also is gen 4 the current?

Finally can I assume all the Rocca's on the muhle shaving dot com website are the current generation (regardless of handle)?

Thanks for your help!

I would imagine that Muhle is selling all Roccas with the latest head. Do a search on here or b&b for Rocca. I recall seeing a thread with photos of the various heads. I had an older gen head and Muhle sent me a replacement head (gen 4 I think or whatever the latest is) for free.
