[Fulltiming]

From model years 1997-1999 there were a total of 101 Newell built. The last non-slide Newell built during this time period was #507, a 1999. During those three years, there were no Newells built in 1997 less than 45', 3 in 1998 #470, 487 and 496, and 2 in 1999 #511 and 526 that were less than 45' long for a total of 5 coaches. Since I don't have 100% complete data, I know that 470 had a single slide but have almost no information of 487 and 496. In 1999, both 511 and 526 had 2 slides.

In summary, the non-slide 1997-1999 Newells less than 45' is a maximum of 2 and likely 0. #487, a 41'0", and 496 a 39'3", are the only possibilities and I have never seen either of those listed for sale. The only good news is that virtually all of the coaches in those years had the Detroit Series 60, #509, a 1999, had a Cat C-12.

If you go back to 1996, all were non-slide except #436, the first single slide and virtually all had the Detroit Series 60 but most were also 45'. 1996 had 5 coaches less than 45', #405 was 43'6", #411 was 41'6", #421 was 42'6". #428 was 38'2" (no tag), and #434 was 42'6".  EDIT: as noted in David post and my post below, there were 7, not 5, coaches in 1996 less than 45'. Add to the list: 426 is 42'6" and 427 is 42'0"

You are truly looking for the unicorn.
