The picture on the box looks nothing like the filter I actually got. The seller fiddled with several boxes and filters before we got it right, so maybe a mismatch.
The filter has a marking on the inside: A060B6 37
Part# on box: E-3226
The filter had to be notched on the inside rim for the four mounting "pillars" to fit, or rather the other way around. If you don't it will be more square than round.
Many thanks, I found the filter listed under E-3226 on image tag below. £35.99 delivered in the UK.
Any hints on how you made that very neat cover?
