Gillette Big Boy DeLuxe From Canada have ?

[Bobbers]

I was going thru some of my razor and noticed I have a Gillette Big Boy DeLuxe that was made in Canada and it has not serial number on it. This is my only razor from Canada. The razor weighs 84 grams and 3 7/8" long. In good shape but does have a crack in the tube. I think it is from 1930.
My question is, is this information correct? Also why no serial number?

New Deluxes were produced in two batches, from 1929-30 and then a few years later, from around 1935 till end of the 30ies.
There is some evidence that the production of New razors ceased in 1930 when the Goodwill was introduced and was only picked up again after the Goodwill production ended.
Iirc 1929 De luxe razors had only serial nrs, 1930 serial and patent stamp, the mid 30ies models had only the patent stamp.
