The Angelus-brand push-up came as a 58-note instrument which, as you
went up the [price] range, came fitted with an internal rank of reeds
(as Dan Wilson pointed out yesterday).

This reed-fitted pushup was known as the Orchestral Angelus, and the
keyboardless organ could be played solo or in tandem with a piano.
Rolls for it are the black crocodile-type boxes marked Angelus &
Symphony -- these play on both this push-up and also the Symphony.

The Symphony was a 58-note roll playing organ just like the Aeolian
Grand.  The only difference is the rolls are 10-1/4" wide instead of
10-1/8" and are spooled bottom-to-top, back-to-front, with a thinner
drive lug on the left hand side, just like the 65-note Angelus piano
rolls.  You can reverse the rolls as Dan rightly said, but I do know
some collectors have experienced minor problems with the 58-note rolls
fitting into Aeolian take-up spool which are particularly 10-1/8" wide.

The Angelus also came as a 65-note push-up and I am told that, just
like own my 1907 player piano version, the 65-note pushup came fitted
with facility to play the 58-note rolls (hence Angelus & Symphony on
the roll labels).  The Wilcox & White Angelus and Symphony range came
in all versions of all varieties, it appears!

As regards it's rocking tablet method of speed control, I think the
system very easy and effective to operate.  (I expect pages of offended
email to follow now I said that! ;)  Seriously, it's probably just down
to what instrument you are used to playing on.

Aeolians tempo lever also seems rather crude to me.  The Angelus has
two;-  one you set just like an Aeolian.  The tablet floats level when
the player is pumped.  Pushing it left or right levers the governor to
over-ride the primary speed lever, thus decreasing or increasing the
speed with a graduated effect.  By depressing it fully to the left you
can pause the roll, and releasing your finger immediately restores the
roll to whatever speed you set it to start with.

On an Aeolian you'd have to flip the lever left to pause then instantly
swing it back to the exact same position you started from.  Doesn't
sound that easy, does it!

The Angelus sustain lever is located on the immediate left of the
tablet, so in playing you have your right hand thumb on the sustain
lever which pulls to the right, index finger on the left side of the
tablet and middle finger on its right -- perfectly simple!  Your left
hand operates the accenting buttons.  Still, practice makes perfect,
as we all know!

I've been preparing a short bit on the Symphony rolls for a few weeks
(pictures, labels, etc.) and will have the URL ready in a few days more
so you can see a bit about them.
