There's a notch in the tonearm where you can remove the reproducer, you have to rotate it all the way to the left.

Re: How to deal with a Seized Ultona reproducer head ?
Thanks to all for the replies regarding my Ultona project ! 
I had a free day yesterday, so I decided to pull the whole tone-arm and put it in the freezer.
The machine is presently in my unheated garage, and temps have been in the low to mid 20's (F) lately.
On my way to the cellar, where the deep-freeze is, I was looking-over the whole affair, and began to try to move the Ultona head.
I decided to remove the spring-loaded detent pin from the Edison side of the head, to elminate any interference from that, and after some application of lighter-fluid to the swivel joint and some persistence, the head finally budged slightly, and I was eventually able to work it off the tube.
The pot metal is not cracked, but apparently the tube was swollen just enough to jam in the reproducer body.
It appears to have been tightest between the holes in the sides of the tube and the collar for the detent pin.
About a half an hour with some 400 grit automotive paper and a jewelers file, and repeated fittings with the reproducer head allowed me to polish things down enough for a workable fit.
(The arm never made it to the deep-freeze, by the way...)
As dark was falling, I trotted back out to the garage with the revived tone-arm and a Diamond Disc, installed the arm, and attempted to play a Billy Murray - Ada Jones DD... unfortunately, the Brunswick motor really didn't want to run in sub-freezing weather...
but the Ultona head seems to work fine.
I took some pics of the project and will try to put together a post about the project on Tech Tips.
The machine is a Brunswick 117 upright, by the way.
Cheers !

Re: Seized Ultona reproducer head successfully dealt with !
Congrats on getting your Ultona taken care of! I too am pretty new to the forums; I just got a Brunswick 112 upright a couple of weeks ago, with the three-way Ultona. Mine thankfully wasn't seized, but I'm shipping it off for replating and I'll be having the usual rebuild done at the same time. The motor on mine is also in need of a new spring or two, so I have to wait now - but from the little I heard with a standard 78, the Ultona is capable of some pretty impressive sound!

When I get home, I make a decision: play the 1929 Atwater radio, the 1929 Philco radio, or the early 1920s Brunswick phonograph. When the power is out - it's EASY!

I think Ultonas sound great once they're rebuilt. I really like the sound mine has, even on Edison Diamond Discs.
