I'm wanting to buy a vintage English razor (probably many) but there are just so many maker's out there. Some of the ones I've been looking at are:
KROPP
CLEMENTS
MAPPIN & WEBB CO
MARSHES & SHEPHERD
JOSEPH RODGERS & SONS
FREDERICK REYNOLDS
TAYLOR WITNESS
JOHN HEIFFOR
GEORGE WOSTENHOLM & SON
JOHN WRAGG
WADE & BUTCHER
GEORGE BUTLER & CO

What are the top 5? I suppose these are mostly Sheffield steel which was renound for good quality. Are there any really sought after rarer manufacturers I should be adding to the list? What are the scarcist and and does rarity mean much higher price?
