Hi. I just purchased a Laubin oboe on eBay (gasp!) and it arrived today.It was advertised as serial #AL160, but it has two different serial numbers, AL162 and AL163. The seller tells me that the three parts came like this in the case from Laubin. I am doubtful. Has anyone ever heard of this, or is this just one more reason I should stop buying on eBay?
