I am buying a used razor from Wallapop with a paddle strop included for 80 euros (£70)

Brand new the razor retails for around £110.
As you can see, there appears to be some discoloration which they claim is not rust.
Not sure but second picture it looks like blade is either warped/twisted or ground to buggery. It does not look straight either way.
Maybe someone more knowledgeable will chime in.
If you are looking for a straight, you will not go wrong with getting in contact with @Fergiebilly .he might have some for sale. that's who I got one from, and I know there is a lot of happy customers of him on this site and beyond.
