"new" razor

Still trying to identify...
It's a Gillette TTO

Below it have the words:


"J" /----\ "1"
|knob|
"Gillette" \----/ "England"




well
It's a Gillette Knack 19?? or a Gillette Tech from 1964

info extracted from: http://www.geocities.com/safetyrazors/gil_ser2.htm
and http://wiki.badgerandblade.com/index.php/US_Gillette_Dating_Information

for me makes more sense that it is a tech... but I need to search a little further..
