It just has character, lovely actually.
Never to discourage a FG set-up on such a proper frameset but my town bike has an AW/3 cog cyclo set-up that is near ideal for it's purpose. I'm sure you have another candidate for that kind of IGH set-up.

Excuse the non-FG pic, it's actually raining so mudguards have been fitted on the International.
