This is the only other picture I have of the interior of the shower car. No idea on the internal arrangement. The fact that the location is known as "boiler springs" might relate to a small boiler used externally to heat shower water, or not. The #23 is what Ron Harr put on the photo files which is consistent with the numbering on other BWP camp cars. Here are a couple more shots from the later Ron Harr's collection of BWP car #21. No idea where or when these photos were taken, nor if this car body still exists
