Alright after a slight break in action I'm back at it. After taking a good look at the steam lines under the car we decided that it would be the simplest to take the superheater out well still connected to the steam line that ran to the engine. The fitting on the engine side was corroded pretty good so we had to apply some heat but after that it came off with relative ease.
Once we started removing the insulation from the pipe it became apparent that none of these pieces were going to be reused. The superheater has 90 degree fittings welded on each end and looks to have been made of a thin grade material; most likely tube. There is a short section of pipe with threaded ends attached after that which must have been where there was once a steam loop. The main section of line running from the superheater to the engine had been replaced by a 1/2" stainless steel tube welded to black iron pipe on each end. I'm amazed it had lasted this long...
To top things off, the 90 degree fitting that threads into the engine was only finger tight which makes me wonder if I had a major steam leak back there that I just hadn't noticed.
Next step is to start construction on the superheater and the feed water heater that goes in the smoke bonnet. I'll be happy to turn the corner on this project and start putting it back together.
