Anyone know anything about Whitestar / M.J.Newman Southampton or The Celebrated?

Hi Folks,

I picked up a two razors on eBay to practice restoring. I thought I'd see if I could find any history about them and turned up nothing.

One has WHITESTAR on one side of the tang, and M. J. Newman on the other - nothing on the blade itself. I can't find much at all on this one.

The other has nothing on either side of the tang (apart from some very deep pitting!), but on the blade it has The Celebrated and underneath it Sheffield Hollow Ground and a little circular Special Steel logo - could this be a Mappin and Webb.

UPDATE - I've just found this, and this is the blade I've got :)

Thanks!
