Have you emailed Howard Levy at Bexley. I'd start off at the horses mouth & work back...lol.
Have you seen the new Bexley 56? Looks like a RHR Waterman 56. MMM-MMM-MMM!
I like the Posideon in tortoise as well. Howard does some amazing stuff. I used to have a HR Olive ripple 51 with a broad nib he made. Truly amazing work. I still kick myself for selling it.

I hadn't seen these before Jack. It feels like a Conway Stewart & a Waterman 100 YR pen got busy. Looks like a solid winner to me. Dare I ask how much?
