Best of luck on that search, I was the mechanic at a pretty big stihl dealer that would have a lot of obsolete stuff come in from 2009 - 2012 and I only remember one 042 coming into the shop, and no 048s. Lots of 041, 056, 075 and even 090 saws came through but those two nobody seemed to have. Heard it was the forest service that mostly bought the 048s when they were making them.
