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!'
