For sale: a pair of HP Combiplan tanks in good condition. All parts, original boxes, and manual are included. I used these for several years, and at the height of my 4x5 activity I was developing 12 sheets at a time with these tanks. One of the top clips has a break but hasn't interfered with operation. There is one spot that's a little leaky, but I just used it on the top, where it doesn't really matter. Otherwise, everything is in top shape.
Asking $90 for the pair, plus shipping, to Continental US.
Sorry, not sure why the photos are upside down. If you purchase these, you can simply turn them right side up.
