Those Middleburn cranks have a LOT of corrosion marks, including bubbling from galvanic action around the inner drive-side part of the spider, and the aluminum is flaking around the pedal threads. What is up with the discoloration and corrosion on the non-drive-side crankarm? It looks like what happens to a forged crank when we have to torch it to remove it from a bottom bracket. Some ham-fisted idiot has been using a screwdriver on that spider lockring as well, instead of finding the right tool. Some of those marks on the inner drive-side right next to the BB spindle taper look like the same idiot removed the cranks with a screwdriver or a punch. That's not chain-suck. Good luck with those, I would have run away, personally.

Phil,
There are other Middleburn cranks listed, and some are rather hammered pretty badly as you describe. The ones that were used for trials are beyond hammered.
The ones I purchased early this morning are no longer listed, and they are kinda clean and unused to the extent that the chain rings might still be good, but I bought them for the cranks.
On my cranks the non drive has some shoe rub on the crank arm but nothing near the square taper. Pretty much I bought them because they were rather clean and remarkably fresh. I suspect that the chain rings are the first original ones ever mounted, and like I said they don’t seem to be worn.
There is a set of cranks listed that the seller says is good, but zooming in shows a stress crash in the corner of the square taper on the drive side. Much of the cranks listed to me were beat.
What I find interesting is basically people can sell junk. Sadly, things must be bad in England I suspect.
