this is definitely not a #77
it is a ball end NEW. there are many different sets with this razors. Oxford, berkshire, federal, regent. ist up to you, cause it depends on just the case
those sets were made and dsitributed in Canada too... like in France (importet only), Germany (importet only) and UKExcept the razors in those sets were made in the USA.
This head looks just like the Canadian #77. I am not sure if it came in some other case/handle combination or not.
@OP: Nice find!
