[Phono-L] Advice please - holes in cylinder surface

[Chris Kocsis]

I just got a cylinder I won on eBay (Edison 9100, Bob Roberts' Everybody 
Works But Father) to replace mine that cracked.  It was advertised as in 
excellent + condition, and as I pulled it out of its sleeve it looked 
like it was.  But as I turned it to examine it closely, I found a 
strange, almost patterned number of deep circular pits among the 
grooves.  I'm afraid to play it in case the stylus catches in these 
holes and gets ripped out.  I'm attaching a picture.

I would appreciate advice (as well as any information on how these holes 
could have formed -- I'm not an experienced collector, but I've never 
seen anything like them before).

Many thanks,

Chris
