I have almost finished my Ridgehill CNR wood sheathed caboose kits, all wide window spacing. To finish up, I need to make and install the splash guards on the end railings and add the grab irons to the eaves. The narrow window spaced one was scratch built out of styrene. Two have Kadee couplers and two have Sergent. All have NWSL wheelsets of either code 110 or P64.
