Mr. Hunter,  First, congratulations on your find! I have never seen
a Peerless Wisteria orchestrion in person, nor have I heard one.
Supposedly, there are about five or six known to exist, including one
in the Sanfilippo collection, and one which Mr. Tim Trager has for sale
on his web site:  http://www.timtrager.com/photo.htm 

Although I don't know that anyone has done a formal survey of Peerless
and Engelhardt and National instruments, my own informal survey suggests
that there are several Peerless O-roll orchestrions known to exist:

1. A Wisteria in "tiger oak" case that was sold by Orange Coast Piano
in California about a decade ago.

2. A Wisteria in the Sanfilippo collection.

3. A Wisteria formerly in Svoboda's Nickelodeon Tavern, currently for
sale by Tim Trager.

4. A Wisteria once owned by pioneer collector Tom Sprague, perhaps the
same one as one of the above instruments?  (Illustrated in Bowers'
"Guidebook")

5. The Wisteria formerly owned by John Maxwell.

6. The Wisteria you are currently considering.

7. An Arcadian in the Sanfilippo collection.

8. An Arcadian formerly on display at Bellm's Cars and Music of Yesterday
in Sarasota, Florida, but sold decades ago.

9. An Arcadian formerly owned by Bill Stackhouse of Napanoch, New York,
and illustrated in the back of "Put Another Nickel In".

10. A DeLuxe (two ranks of pipes) in an Arcadian case, sold by Hathaway
and Bowers in the 1960's and listed in one of their catalogs.  Perhaps
the same one as 6 or 7 or 8 above?

11. A DeLuxe in the standard design case, now owned by a prominent
Indiana collector.

12. Another DeLuxe, also in the standard design case, now owned by
a prominent Oregon collector.

13. A DeLuxe in the non-standard(?) "fancy" design case, in a prominent
Southern California collection.  This is the only Peerless O-roll
orchestrion I have actually seen in person and also the only one I've
heard.  It has the most wonderful piano I have ever heard in an
orchestrion, with the richest bass of any upright piano I have ever
played.  (Oh yes, I got to hand-play it).

14. Another orchestrion, either Arcadian or DeLuxe, in the same style
"fancy" case as #12, but in the Sanfilippo collection.

15. A National Elite model H with violin pipes, (and of course drums and
traps under the keyboard), sold by Hathaway and Bowers in the 1960's.

16. An Engelhardt style F-3 cabinet orchestrion owned by a collector
in Belgium (I'm not sure that this uses a Peerless O-roll though):

In addition to the instruments in the list above, there are at least
two gutted-case Peerless orchestrions known to exist:

(a) An instrument offered for sale by Gordon Stelter in 2005: "Peerless
orchestrion, from 1895, everything up top gone, bottom player works
complete. $600 OBO."  (Obviously the date of manufacture is wrong.)

(b) An instrument, possibly an Engelhardt model B, C, or D in a
non-standard case, owned by John Gourley in the 1960's and illustrated
in "Put Another Nickel In".

To my knowledge, except for #16 none of the above instruments have been
converted to play any other kind of roll than the original format
Peerless O-roll.  Many of the instruments in the above list are
restored and currently play well.

As to rolls, I would first check out the list of Peerless O-rolls
currently available for sale from Valley Forge Music Rolls in
Pennsylvania:  http://www.valleyforgemusicroll.com/styleopeerless.htm 

They apparently have six big rolls currently available, including
ragtime, blues, and patriotic selections.  You will note that they also
offer a custom recutting service, so those tattered, torn, unplayable
(or whatever) rolls that you say come with the Wisteria you considering
can be scanned and recut!

I'm sure if you can get some of the owners of the above Peerless
orchestrions interested in the rolls you have, then they might perhaps
agree to help you foot the bill to get these very rare rolls recut
(in return for getting recuts for themselves)!

Besides Valley Forge, the only other time I have heard of these rolls
being recut was when Terry Borne had some of them done in the 1970's.
I think Play-Rite was the company that did this, but not 100% certain.

Ken Volk had 28 Peerless O-rolls (recut by Terry Borne) for sale in
2005, but I'm not sure whether they're still available:
  http://www.mmdigest.com/Archives/Digests/200506/2005.06.01.11.html 

Peerless O-rolls are spaced 7-holes to the inch, the same spacing
as the Peerless Elite.  Although neither of these formats are common,
there are still enough Elites and Peerless O-roll orchestrions and
rolls around that it might be worth the expense to have a perforator
set up for this spacing for a while to do a run of several of these
rolls.

At the asking price the seller in Pennsylvania wants for the Wisteria,
I'm sure many people reading MMDigest are already wanting to buy it
if you turn it down!  Even though most collectors don't even know what
a Wisteria sounds like, they seem to want one anyway.
