I can't seem to find info on this particular razor I have. The handle is a cream colored plastic with silver end bolsters, and could have been put on the blade later, however the blade itself is marked 'Tungsten Steel' and has the W.R. Case & Son's' curved in an arc on the opposite side and 'Bradford P.A.'. There seems to be no mention in the Jim Sargent reference book I have.
Thanks
Aaron
