Pete, on the STERN site, under MEDIA, there are some really great STERN videos to watch. On one of those videos it talks about the production line being capable of 55 units per day. This video was taken around june/July of 2011 so they may have updated the line to cater for larger numbers since then. Check out the Stern site again cause there are some great videos under the media section. From memory, i justed cclicked "All" and a big list of videos came up !
