A bit confusing. I hope there are more answers to this. There are  
early acoustic records where repairs can be found using a loop. Also,  
there are white label special ordered pressings from HMV of one of  
the Pattis which, while they look like they are original, are clearly  
dubs. I only know of this one.

If a dealer is doing what is described below, he is clearly  
misrepresenting what he is offering for sale.
