Can anyone help me with how to find the value of a vintage Yankee Cutlery Razor (No.190R with Box) engraved with Mansour el-Hilow & S. Joseph M.I. Germany. I have been trying to research it, but am having trouble finding any sources for it... the vintage razor seems somewhat unusual... but am not a collector so don't know where to even start looking for a valuation. I would appreciate it if anyone could help. Thanks in advance ... Mike... if you want to email me- cattuzzo77@gmail.com[/email].
