Old-fashioned razor (Castle MK40)

Is there any market for a pre-loved cut-throat razor (with a new blade, of course). I bought this from The Store as an alternative to plastic disposable razors, but actually it really isn't suited to tender female armpits, and every time that I have tried to use it, the bathroom ends up looking like that scene from Psycho..... It is very postable, should anyone want it, but not want to schlep all the way to Denmark Street to pick it up.
