So I’ve collected today. Happy to report there was no issues.
Guy that was selling them was a removals guy and had no idea about motorbikes, might explain the cheap price. Also as a bonus, they are brand new, seriously. The inside is untouched and just a couple of minor scratches on the outside which is obviously from storage.
Spent some time coding the barrels and I’m just missing one wafer (number 3). Still locks but not as secure as it could be. Will be good enough to get started.
