Be Very Careful with this guy
About 20 years ago my Dad took an Austrian clock in for cleaning and repair. One of those with the four brass balls thats would rotate then counter rotate. The kind that was replicated in the 70's and 80's. Anyway, when he went back to pick it up these people said they accidently gave it to someone else who had their replica being repaired. That clock was over a hundred years old. The people recognised a treasure and they stole it.
