Sam,
Number 19's boiler is in good shape considering she was left in the elements for nearly 20 years with the lagging on. I don't know of any major repairs that have had to have been done to her. Most of it has been run of the mill such as the firebox repairs she recieved a few years back. We anticipate that number 20 will be in similar condition, and from a rudimentary investigation it appears to be. In our favor, the organization had the foresight to remove the jacketing many years ago, then clean and paint to boilers to keep corrosion to a minimum. The boilers arrived in fairly good shape, and we do our best to keep them in better shape,
Thanks, Taylor
