Many thanks George for this info.

I am surprised the ELP won't play lacquers, but that ends the  
discussion!

Why the broken piece won't fit snugly against the larger piece from  
which
it was broken is a real puzzle and something I have never encountered  
before,
and I have a lot of experience with broken records.

It means that if I get the grooves to line up perfectly at the rim on  
one end of
the broken piece, the grooves will NOT line up on the other end!    
Dealing with
a gap is no problem as long as the grooves on both sides of it line up  
reasonably
well.

I can tell the lacquer has shrunken slightly, and I can deal with  
that, but glass
does not shrink, so why the large pieces won't fit together is truly  
inexplicable.
