There's a few differences between the Pacemaker Speed Graphic and the Anniversary Speed Graphic. I wasn't aware of those (quite essential) differences and bought the 'wrong' camera for a lens on lens board that I own, thus ending up with both models.

Which is your benefit, since it allowed me to do a side-by-side comparison!

 

The Pacemaker camera looks like this:

 

It has a smaller lens board (made from metal) than the Anniversary. It also has a shutter release on the body (the ribbed button on the edge) and a metal ground glass hood that pops open with a 'kaz-zing!' 

The Super Ikonta series from Zeiss Ikon started their life in 1934. In that year, Zeiss Ikon released three Super Ikonta cameras for the 120 format. They were remarkable cameras and continue to be so until present day. A good Super Ikonta has unprecedented image quality, they are the Rolls Royces in build quality when it comes to medium format folder cameras. 
 
The three cameras that were launched in 1934 very nicely had their own strengths and there was a model for every wallet.

The Horseman Convertible 842 camera was made in the early 1970s. This Medium Format camera with a 62mm wide angle lens was a novelty. It equals a 32mm or even a 25mm wide angle in the 135 format! The camera remains a rarity to this day, sometimes these cameras surface on eBay or on camera shows. Judging from serial numbers on the lenses, there were less than 5,000 cameras made.
