Tommy Armour 845s?

[Millrtme]

This is my first post here and I did some searching and didn't find anything. Back in the day I played a set of TA 845s of the 1988-1998 vintage. The other day I came across a used set at the local shop for $9.99, I couldn't resist. It isn't a perfect matching set but for the price who cares. I believe these are also the same vintage. Now I have a few questions. While trying to complete the set I have found some clubs have "Pat Pend" in the cavity but mine have "Patented". Also they have 3 bars on the hostel and the middle bar is white. Does this mean anything specific? Just trying to do my best to complete the matching set. Any info is helpful and appreciated.

white line in the middle is neutral lie.

Would you mind elaborating on the "later model"? Thanks
