The Muley Type Caboose from the diagram book at: http://www.frisco.org/shipit/index.php?threads/frisco-caboose-diagrams-museum-version.4835/ Included data: It would appear that there was a wide range of car numbers (224-939, non-consecutive). Would anyone have? A picture of one that they would care to share of this type? A list of numbers rather than the range? Original build dates? Models built? Apparently a "Frisco1522" named "Don" posted one on Trainboard...hint, hint! Thanks, -Bob T.
