I recently purchased the dark brown shell RL Marlow SWB from RL online (made by C&J). I took advantage of the 25% off promo they were running ($850 less 25%). They will serve as a very nice brother to my ravello SWB. My Marlows are quite a bit darker than even my cigar models (which I was expecting).
For those on here that want the elusive ravello SWB, but can't seem to get lucky enough to track them down, I would highly recommend giving the Marlow a shot (if, in fact, you are willing to go to a darker brown).
I went TTS. The fit is somewhat similar to the Tremont.
A good weekend to one and all.
The dark brown shell on the Darlton/Marlow is a fantastic shade. On some days I like it better than cigar shell.
