Free Traffic Legal Advice

I came down the road where the sign is twisted round, went round the mini roundabout and parked up.

I've parked there before without any issues, not sure when the last time was though and I don't know when they brought these restrictions in.

Council: Redbridge council
Alleged contravention: Code 16, parking in a permit space or zone without a permit.
Location: Wellington Road, Wanstead, Redbridge

Just received a PCN on car windscreen parked on a section of the road with no obvious parking restrictions.
The road has a section of double yellow lines, a section of single yellow lines which also has a parking restriction sign, and then a section of road with no markings or signs.
The car was parked on the section of road with no markings or signs but received a yellow ticket on the windscreen regardless.

Photos attached of the layout described above including my car parked as well as of the PCN. My car is the grey VW polo.

I would like to make an appeal and would like advice on the best way to approach this. It seems fairly clear to me that if the sign applies to the section of the road that the car was parked on, then these signs and markings are not adequate and are misleading because the single yellow line clearly ends before where my car is parked, however, I am quite willing to believe that putting just this information into an appeal may well not be accepted and therefore I would like advice on how best to approach this.

Please let me know if I have left out any required information, thanks in advance for any help you can provide.

Struggling with attachments unfortunately.

I will check signage in person to ensure still same as what Google maps shows.
