Scania R580 cab with a difference

[6239chester]

Dear all,
I'm on a hunt for somebody who would be able to make a R580 Topline cab for a 4x2 project on the bench at the moment...
The difference being I would like it to be 1/11.3 scale.
This may be an odd scale for most of you out there but my family are heavily involved in 5 inch gauge miniature railways and I've always thought as I'm used to building in 1 1/16 inch to the foot I may aswell do the wagon to that scale.
Many thanks,
Tom
