Looks like I spot Paul's LGP-30s there as well. Good for parts, but I understand the drums are unsalvageable. 

I'm at a temporary standstill with mine due to an issue with two of the recirc registers, problem believed to be at the drum. Unlike a lot of 'other' gear, I have to tread lightly on this stage of the troubleshooting and have been keeping my eyes out for the correct miniature Winchester connectors to be able to switch in/out the heads. So, not a lot of progress has been made since last spring, but I did bring the machine up last month to exercise the bearings and Flexowriter. Also fabbed-up and installed replacement 'wings' for the control panel which are missing from practically all of them, so it's at least looking better.

Jurgen Muller's LittleGP-30 kit has been fun to put together, now I just need to brush up on my programming.

I also had the fortune of seeing the University of Stuttgart's 100% functional LGP-30 this winter...some pics here:
