The last two tanks of the ones I bought to start this site are now on eBay. They are a Kent 20 (Item number 181318876231) and a Rondinax 35U (171236914495).
That leaves me with a Rondinax 60 to use for the 120 film from the Rollei, and my Rondix. Although I have no 35 mm film cameras at present, the Rondix could be useful if I have to test such a camera in the future.
Why keep the Rondinax and not the Rondinax 35U? Smaller, easier to wash and keep clean, don’t need the thermometer in a centrally-heated house, don’t need to short cut lengths for processing.
