I probably don't actually have anything useful to add to this thread but hell, I'll still add it. I love the EK because of it's elegant simplicity and I think it is one of the reasons it's image has kept a fascination even in modern society. I have 4 EK's but they are all of way simpler minds and less costly because as a business owner I can not rationalize spending to much on a "hobby" sadly.
But to the point... the above is probably the most elegant fastening system I've ever seen on an EK. I did not know the maker or the sheer beauty of the "back" of this type of EK1. So thank you guys for showing that not only the front is stunning but that sometimes the back is even better.
