I'm selling an Ilford 500 Multigrade system I bought several years ago from a lab that closed. The system includes the 500H head; the power supply; control panel (but no foot switch), the 4X5, 6X7 and 35mm mixing chambers (which show some scuffing on the acrylic surfaces); the correct adapter plates for the two smaller chambers, a well-worn exposure probe, and the manual. It's seen a lot of use but seems to be in fine operating condition. I've tested the components, and they all work, but I've never been able to mount it to my Omega D5. I thought the side mounting brackets were for an Omega, but they're not (they won't fit a D2 either). Each side of the head has two small horizontal studs, on which the enlarger 'lifters' can be attached (see detail photo) and tightened. I've measured, and the distance between the left and right brackets is a bit over 13.5 inches. I'd like $225 for the system after shipping, which could be pricey--all the components weigh close to 35 pounds (unboxed), and they'd probably need to go in two boxes. My best guess for ground shipping would be about $60. I'm in Minneapolis, and I'd be willing to drive an hour for a buyer in this region. And if anyone knows more about which enlarger this fits, I'd love to hear from you. It sure looks Omega to me, but I'm stumped.
