Please help identify

Hi All: I rediscovered three razors that I had acquired some time ago. I have been able to identify the first two but would like some guidance on on the third as well as some information on their aprox age and value. The first razor is a Henry Sears & Son 1865 Queen 5/8


The second razor is a George Wosenholm & Son Original Pipe Razor

The third is very interesting as it is marked Joseph Rodgers & Co (not Sons!!) It is marked Extra Hollow Gound on the facing blade. The reverse has a strange mark: 8cin over 109

So there you have it. Any help that you may provide would be greatly appreciated. Thanx!

The 8cin over 109 on the last razor appears to be hand-etched. So it may be a former owner's personal code, or an inventory coding.
