Greetings all,  I'm seeking information as to the roll widths and
The holes per inch or per centimeter of the following systems:
Pleyela, Virtuola, Stella, and the Philipps P.A.

I would also like help in identifying other firms, besides the
system manufacturer, that made reproducing rolls for Artrio Angelus,
Empeco, Philipps, Pleyela and Virtuola.

This may be gilding the lily, but some of the research I've done
has resulted in conflicting or incomplete answers.

Thanks in advance,
John McClelland
