Help with faded name in handbag?

I bought this beautiful vintage suede handbag, and I am having a difficult time making out the name printed on the lining in gold. Much has rubbed off, but in the right light you can still make out some letters. It looks to me like the letters are “FS-a-k”. I contacted T&F Slack Shoemakers, but they said this is not one of theirs. Please see the photos - name is visible up close in two. Any ideas on this label? (Also, is that lucite on top?)

 

Absolutely looks like tortoise lucite topper but I can't make out the label.

 

possibly Paoli...

 

Looks like Block, also resembles Block styles.

 

That’s it! Thank you!!!!
