Ball-end NEW, long comb, Made in Canada. It predates the NEW patent in Canada. I think that means 1929-1931.
You could epoxy the handle if you like. I would not bother unless it impairs use of the razor, but I generally use NEW heads with other handles anyway.
Yes it is a Ball End New. If you can find a short comb guard for it it will be even more aggressive. Nice score, these are very popular amongst us B&Bers.
