That sucks Bucky ... because I REMEMBER that jingle.

Trav, I don't know what those numbers are. They may be patent numbers. With the better pics, I think it's pretty well established you have a "New" and (other than on the blades) Gillette quit using date codes in 1930 (started again in 1951).

You can only narrow it down with a little guess work. IF those blades came with the razor (probably did not) it would date the razor between 1932 & 1940. King Camp Gillette (yes, that's his real name ... the guy pictured on your blades) died in 1932 and that's the year they came out with the Blue Blade (some say '31) and they were packaged like that until 1948 when the white plastic dispenser was introduced. The "New" razor was made between 1929 and 1940 (some aren't sure if '40 is the correct cut-off date, but it's pretty well accepted as fact). So basically, your razor dates between '29 and '40 ... with no date codes that's about as close as you can figure.
