Gillette Blade dating

[Mark1966]

Sorry for possible noob question but I know you guys are patient and kind!

I'm after blades to complete a 1966 L1 Aristocrat set. In another set from the same year the blades look like this:

Now I know that razors are date coded but is there any way to tell if blades are manufactured at a certain time? I'm probably a bit OCD about ti but I'm really trying to get a fully matching L 1 set (my birth year and quarter) so give to me son in a few years time.

Thanks in advance!

Gillette Blades have the same letter code date marking as the razors do.
So a 1958 Razor is coded D, and Blades from 1958 are also coded D.
1966 is letter code L, as you can see, L1 is on the example from Achims Site(Thanks Achim).

COOL - thanks Phil (and Achim who has truly the most amazing collection)
