i am coming up with loads of daft questions lately, so here's another one for you, how come razors end up as nos, i have seen some as old as perhaps 70 -80 years but classed as nos, what has happened over the forgotten years with these razors, did they not sell when sold originally and the company just stock pilled them, did the company go bust and years later people found them stored away, just curious how razors turn up years later as nos?
