Why would you pay these prices when you can get them from reputable dealers (like Burton Bike Bits) for less money, with a large load of certainty that they're English made? (And you might get them even cheaper yet from Peter's in NL but for the fact that he's out - temporarily, I hope.)
some time ago I brought a set of point from what I thought was from the north of England free post they didn't turn up for age I ask the chap for proof of posting he said he didn't get one eventually they arrived from china
