Follow up Tech question

[VonMises1881]

It seems from the posts made answering whether to use my ball tip Tech I'll definitely give it a try. Next question.

I know they made these razors for a long time, (I've heard 40 years), but is there a way to roughly date them based on the handle? Did they make ball tips for the whole run? The fat handled ones? Really not an important question but it's just the curiousity of the whole thing you know.

Many Gillettes have a letter (representing year) and number (representing quarter) on the underside of the head. Check the wiki, there's a detailed chart explaining the date codes.
