Hi guys and girls,
No, no, it's not like that, I am not trying to take a putter out for a drink, I just want to know the age

I bought this Anser the other day and am a bit confused in trying to date it.
It's has the 85029 area code, but it has no patent number on it.
It also reads KARSTEN in the cavity and not Karsten MFG Corp.
From what I understand from the internet is that Karsten produced Ansers from the 85029 area in 1966 and 1967.
And also from 2000 till now because of the headquarters being situated there.
The patent didn't come through until 1967 I believe.
Since I doubt this putter is as young as from 2000 or younger, would this make this putter an early (non-dalehead) Anser?
Or can anyone confirm the story I heard that Ping Anser putters were also stamped with the 85029 area code later than 1967?
If so what could the year of this one be?
... if I know she's of legal age I may take her out for a drink anyway.

Thank you in advance for any info you have on my new baby.
Kind regards,
S.
