Does Edward Green have a model that corressponds to the Lobb Naseby? It is a two-buckle monk strap, with an elegant, plain toe (i.e., not a cap toe).
I've never seen one, but that doesn't mean that there isn't a model like that in their archives. E-mail them a picture, and they should be able to tell you. You could order the Westminster without the toe cap, but Naseby's straps are parallel and Westminster's aren't.
