Daniel, the larger of the two enlargers looks to be an Omega with the "saucer-shaped" lamphouse, which was designed with a circular fluorescent lamp for graded papers. I have the E6 (5x7) version which I converted to LEDs for use with VC papers. FYI, if you're ever interested in such a conversion, I posted this lengthy thread some time ago:

Also, when I built my darkroom I hung a couple of fluorescent fixtures for room lighting; then I noticed they left a very dim afterglow from the phosphors for several minutes after being turned off; so I switched to incandescents. I found out later this is a common problem with fluorescents.
