Creda Compact Reversair Sensadry System?
After hours of speaking to various idiots who insist the machine has a model number I have discovered it is decribed by Creda as a "3kg model"
The genuine belt part number is: 1741117
Espares part number: ES131871
On Ebay for £5 delivered or about £12 from online spares places.
HTH.
