Last year, I discussed the Connoisseur Catalogue and indicated that a new edition was being prepared and would be made available online.
The time has come. Six Machin chapters (plus one covering pictorial regionals) have now been posted on the website at www.connoisseurcatalog.net. And, for now, they are free!
I haven't had a chance to review them myself, so I'll post comments later. I did want to let everyone know.
