Need help identifying a new Webley MK VI?

I'm starting my own Webley topic for a new revolver I picked up yesterday.

It was sold as a Webley MK VI revolver in .455, but shaved for full moon clips. Appears to have been refinished which removed the maker's marks on the left side of the frame. What I find most unusual is that it only has a 5 digit serial number.

Does anyone know what I have?
