Scanspeak driver age codes - How to read?

Hi, i bought 8555-10 scanspeak driver from sale.
Seeing lately post about driver failures due age, im getting a bit of cold feet.

Can anyone tell me how to read age codes of scanspeak drivers?
I would like to know age of this driver, so i can make decision to keep it or return it..

One example of how to read is here, this is from soundimports when i had problem with tweeter:

PW seems to be age code, first number is week and second is year.
But does this mean that my 8555 driver is 14 years old? So only number 9 after week code is clue to year?

Thank you for chatting with us. We are sorry for the damaged label on your R2604/832000. The damage might occur due to packing/ unpacking the tweeters.

The tweeter you have received is not very old; In fact, it is only 18 weeks old. It is produced in week 34 from this tear (PW:342022) and was received in our warehouse at the December 6th together with other R2604 from the same production run (11700):"

Hi, I assume drivers spent all the years in the boxes. Check them visually, the surrounds, the spiders, etc. If it is all ok, I would forget about making worries and enjoy the Classic sound, there is not many options in 8inch cathegory that would come even close for that money.

4pcs of 18W revelators are still ok after >20years in my first diy project - Ekta Grande by Troels.

If it’s any consolation, I have some Focal kevlars with rubber surrounds that were purchased in 1992
and used everyday in my home theater rig with 30+ years of use and still going strong
I do once a year run some armor all on all the rubber
I have extra unused 10” and 7” dvc kevlars with no issues or signs of age wear on the rubber

I have a pair of Scan Speak 13M8636's (Kevlar mids with rubber surrounds) that have been in use since about 1991/92.

They still work fine. The Dynaudio 30W54's that they are paired with (foam surrounds) have been re-foamed. I have always been led to believe that rubber surrounds typically outlast foam but that is likely heavily dependent on exactly what the foam is etc. and the environment in which they are used.
