Photos of C-19's

For modeling purposes, I'm trying to build a portfolio of photos of class 70/C-19 locomotives by engine number to highlight the varioous differences and changes to each engine over the years. Althought there are quite a few images to be found, like those on this site [www.drgw.org]

I've managed to find lots of photos of the three engines still extant but only two poor photos of the 404/344 and none of 405/349 and 408/348. I just received a copy of the book "Locomotive 346 Rebirth for the 21st Century" and it has dozens of period photos of the 346. There must be collections of photos of the other engines out there and I'm hoping you guys can point me in the right direction.

Thanks
