I don't know Cuir Russie (yet), but I had No. 5 edc in the mid-1970's. It had way more longevity than today's edt or edp, smelled way more complex, and my scent recall of it is my benchmark for the way No. 5 should smell. with a sweetness that develops over time. But that's not available anymore. I haven't tried No. 5 in parfum yet, but it's probably what I'm looking for. Sorry, I can't help you with Cuir Russie.
I have Shalimar in eau de Cologne, and I love it. It's rather smoky, and fairly long lasting. It's nice that you can still get some Guerlains in eau de Cologne strength. They are very nicely made.
