Baker boiler for a steam car

​I started work on building a model of the Baker boiler. I have had some plans for several years, but was reluctant to start as some photos I had were different then the drawings. I am not sure if they were all built the same. The Patent drawings show a cleanout system to blow the tubes inside the drum and the only construction drawing shows no system on the top of the drum, just a welded top plate. I know there are about three Stanley’s running and using a Baker boiler but I have seen none without the casing on.
 
Have you seen one striped down? Or do you have any photos of one striped down with no casing.
