I have a 50L keg that I bought from Harpoon and converted for use as a keggle. It has a 12" hole in the top to fit a standard lid and 3 1/2" NPT pipe nipples welded in. 2 are near the bottom for drain and sight glass/thermometer, the third is near the top for return. I'll throw in a lid, ball valve and pickup tube as well. I'm asking $90/OBO. I don't want to ship this thing, so pickup only in Worcester, MA. I'll entertain driving a reasonable distance to meet you halfway as well.
