Well, apparently these are very rare. I happened to find the official
website for Ervin Nyiregyhazi (Mind you, I don't even know who this
man is) and even *they* are looking for the items you mentioned:

http://www.nyiregyhazi.org/recordings.htm

(Unless, of course, you're the one who maintains the website, in which
case, I apologize) I'll keep looking, though...

Yes. I'm the webmaster for www.nyiregyhazi.org.  Nyiregyhazi was my
father-in-law's first cousin.  I am trying to complete my piano roll
collection.

Just an aside:  That's twice now that someone has given a questioner
*his own website* as reference in either an answer or a comment.

What are the odds??

Hi Aaron,

I’m Hungarian, so a wonderful Hungarian name like Nyiregyhazi quickly
grabbed my attention. It looks like you’ve found every Web site that
ever mentioned his name, not to mention your long-time participation
in a variety of newsgroups. You seem to have been working on this for
a very long time so you’ve probably already seen everything I found.
(I also found lots of news from Nyiregyhaz, Hungary.)

I thought I’d try a different approach for your quest and try to
identify kindred spirits who might be interested in old piano rolls.
You only list The Piano Roll Shop on your Web site. Here are some more
piano roll vendors as well as a couple of organizations that might
have something useful for you.

Good luck.

The Reproducing Piano Roll Foundation shows lists Nyiregyhazi in its
rollography and has the same list of piano rolls as you do. I suspect
you know about them already.

Good Day, aarond144-ga 

Although this question expired on May 13, I do hope you get this
comment.
I did not find what you wanted.  However, I did find that there is a
sealed LP for sale on www.ebay.com that you might wish to purchase. 
It is Nyiregyhazi on Liszt, but it is Ballade No. 2 b.
Since it is a sealed LP, you might want to bid on it for your
collection.
The price is currently about $20, but the bidding is expiring on May
25, so you should go to www.ebay.com, enter Nyiregyhazi as a search,
then place your bid if you want this album.  The ebay page will show
the album cover, back and front.

Good Luck,
Brad-ga
