Column of M601 is 83.5cm from baseboard surface to top. Base is 50cm wide by 55cm deep. Base is on rubber feet and stands approx 6cm off work surface. I think it is more recent than the M600. I saw a big list of Durst products and manufacture dates somewhere on the net. It may have been here, or another photo forum. I've had my 601 for years. It works well, and is solidly built. I have thought about an M605, but the M601 does everything I need. I use it for 6x6 B&W negs with the Ilford filter holder attached. Alex
