Thanks again, for all the responses. Knowing that this is indeed an OLD Stanley,
I will not alter the collar.
However, I don't really want to try and alter the blades either. I know this is
a long shot but does anyone have a spare collar that they would be willing to
part with for a reasonable price? I'm guessing not, because it is probably a
part that often gets misplaced and therefore they are in high demand but just
thought I'd ask.
Also, does anyone know if the Veritas collar would fit on the Stanley?
I'm a simple man. I like pretty dark-haired women and breakfast food.
