Sorry for my delayed reply. I couldn’t see your images until they were approved.
The R/N number on the label (701567) matches the number on the PCB artwork and sticker (2060-701567 and 2061-701567). A little Googling also confirms that this PCB number matches the WD1001FALS (and WD1002FBYS / WD7501AALS / WD2003FYYS / WD7502ABYS).
I notice that the date field has a “V” at the end. I’m wondering whether this may be a refurbished or “certified repaired” drive.
Here is a similar drive with the same R/N number and an “H” suffix after the date:

Notice that it says “Recertified” above “SATA / 32MB Cache”.
Here are other drives that don’t have any obvious recertification mark:

It appears that later versions have different PCBs, ie 2060-701622 or 2060-771640.
Your HD Tune performance graph shows that the width of the band of access time data points is consistent with the rotational latency of a 7200 RPM drive, namely 8.33 msec.
The maximum sustained data transfer rate of 111MB/s is consistent with a 1TB drive that has 3 platters (ie 333MB per platter), so this makes it an older model.
You didn’t show us the component side of the PCB, so I can’t infer its age from the age of the chips. However, the spindle motor has “1138” written on the sticker, so I’m guessing that this may reflect a manufacturing date of Week 38 of 2011, but I’m not confident of that at all. Instead I have a feeling that the drive most probably dates back to 2008 or 2009.
I’m not familiar with WD’s recertified drives, but it would seem reasonable that such a drive should continue to reflect its actual Power-On Hours Count in the SMART report.
