+1!...I love the open comb razors, plus Gillette Aristocrat Junior, Gillette Aristocrat (prices increasing faster than my savings!) - No 16 Set, No 22, etc - the list goes on.
No idea why the difference in the MoD razors. I'd read good reports and thought I'd got lucky getting one in a bargain lot but was appalled by the shave; weepers & nicks aplenty plus lasting soreness. I've not seen an MoD razor like mine though, it has some kind of "champagne" silver painted finish, now with corrosion bubbling under the surface. Silk purse, sow's ear. Don't blame the manufacturer for not identifying himself.
