So, thought I would finally post this now that everything's settled out with this Mac. Thanks to @bobesch I was sent a 15" A1260 he had on hand with a US keyboard. Took about a month and a half to arrive but got here in perfect condition. The Mac is 2.5Ghz with 4GB of ram. I'm running El Capitan on it and it's doing very well. Here's a shot of the Mac and the specs. Based on the desktop wallpaper you can assume that it has taken on the former role occupied by my 17" MBP, which is now serving as a content creation machine.
