G'day all, My US made 1921 Steck Duo-Art grand has the split #43/#44,
as suggested by Dan Wison.  It might be interesting to see if my
(former) 1914 Stroud upright has the same split; maybe the current
owner can enlighten us.

I often play Themodist rolls, presumably with #44/45 split, and I admit
I haven't noticed the discrepancy.  Maybe Aeolian hoped most other
customers wouldn't either when the change was made!

Cheers,
