Interesting, no markings at all, not even 'made in England'.Does it just say 'Made in England' anywhere? I am not expecting any other markings.
I am pretty sure it is one of a large series of contracts that spanned 1970-80's for at least the U.S and British militaries and maybe many others. I have found another example with a different box marked 'B. Sharp Blades Ltd Deer Park N.Y 11729'. The box seems to be early 70's with the same razor set up. This example comes with 'Hammer' Brand S/S blades in packs of 5. These appear to be G.I issue as I have found a whole 100 tuck of them selling separately in a box with the U.S Army designation, 'Blade, Razor, Type II' or similar with an NSN number. They were on the bay about a month ago.Interesting, no markings at all, not even 'made in England'.
A few years ago I bought a 5 pack of these NOS British Techs in the Adams boxes for under $15 each razor. They are now going for triple that or more. I should have bough 15 more at that time. Who knew. I bought them to PIF to new wet shavers, etc.It was manufactured in England, and then oddly imported or sent to the U.S, where they were packaged in white cardboard boxes marked 'Adams Safety Razors.
