Ever Ready 1912? Super Speed? Maybe a Merkur 34C or other Merkur? All excellent and not too expensive. Maybe even a Merkur Slant if you want something a bit different. None should be more than £40 plus delivery
Well, think you found the answer yourself Otherwise the US Aristo, or some superspeed or rocket. New/Modern razors I couldn't give you advice though, so I'll let the other give those suggestions
Go with what started the whole trip! A Gillette '04. You can still find nice ones at a reasonable price. Go for the gusto, get the 1st one.
(the silver plated ones are really nice!)
