Vic,

I have given up trying to find a reliable UK supplier of such genuine FWB spares

I use the below with complete satisfaction :

Nikkonos (Bay Of Flea) :

https://www.bay_of_flea.co.uk/usr/ni...p2047675.l2559

or Foest :

https://foest.eu/index.php?main_page...th=11_12_14_21

Have fun

Best regards

Russ
