Just got my Munton's tanks and other stuff from AB, it was only shipped yesterday afternoon so that was quick! I took some photos for anyone who wants to see. (

These are exactly what I wanted, its stronger plastic and compresses less than the fermenters I currently use. Volume marks on the side are nice although the plastic is opaque. There aren't any vent holes in either tank though so I drilled the center of the lid for the tap addition on one and put a tiny vent on the other end of the top.
Quite a bit of extract in there too! I added a bit of hot water to each tank and rinsed it out into a pitcher, about a kg without the water. After diluting some and checking the SG it looks like I should be able to make 6L of wort at 1.05 Starting gravity. Right now I am heating up the undiluted extract to sterilize it, should be fine in a sanitized glass umeshu jar for a few days while I figure out what to make with it.
Bottled my smoked porter today too; that 100 yen bottle drying rack worked fine without any extra support. I could fit about 25 bottles on it, long necks fit quite well.
