Hi all,  About three years ago (January, 2017) Andrew Barrett of
California posted an article about Schulz Recordo pianos and their
rolls from QRS which were supposed to be 16-step rolls.

I'd like to know a bit more about the rolls (if they looked similar
to half Duo-Art rolls with long chain perforations with perhaps three
or four expression holes being punched at once).

I'd also like to find out if the roll numbers had a letter "A" before
the number (most Recordo rolls had an "M" prefix at QRS).

By the way, is there a tubing diagram that might be available?  I'm
in the process of rebuilding a 72-note Recordo that is only 37" deep.

Thanks so very much!
