RARE Birkinstock Boston Taupe 39 Narrow L8 M6 Original Footbed Vintage? READ

These are authentic Birkinstock pre 2017 with the yellow lettering.  No model # on footbed but these are the Boston style.  Original footbed with all the indentations on the footbed.  Made in Germany has lowercase letters due to age.  The yellow writing on interior is indented in the footbed and not just painted on.  There is an "02" stamped on the inside of the suede   I am not sure if this means 2002 for the year these were made.  The inside of the shoe is stamped 43 4Y.  The size is a 39 ladies women's 8 and men's 6.  The shoe is indicating "narrow" however the original footbed was wider than the current footbed with the soft insoles so I provided photos with a ruler.  I wear a wide shoe and am able to fit in these "narrow" Birks just fine.. Condition: pre-loved.  These are in excellent condition for the age.  The soles show little to no wear.  The insoles show little wear.  I did clean the inside with soap and water as they were dusty from being stored.  One footbed appears a little darker than the other.   The exterior was cleaned with a suede brush and suede cleaner.  The cork was recently sealed as there was a little separation from the footbed and cork which was repaired.  This is to be expected with the age.  The exterior suede is in nice condition. The left shoe has a small circle by the toes that appears darker.  I used the suede cleaner however, it is still there but not as noticeable.  PLEASE SEE ALL PHOTOS AS THEY ARE PART OF THE DESCRIPTION.
