First off, sorry it took so long to respond. got caught up in life as we all do sometimes.
Some very good insight, I always will have more to learn about the way things are done at the C&TS. (and I don't mind losing a discussion or being proven wrong, I'm all the better for it.)
30 days of work sounds reasonable, that's if you had all the parts and materials on hand without finding any nasty surprises when (and if) they get to work on her. My buddy told me that the group who restored the Leviathan has the drawings for the (No. 8?) injector; and with the proper funds a replacement could be made new. And I agree that it does not *need* a cross compound air pump, but said upgrade would be a safety benefit; if you could fit one inside her that is.
Thanks for clearing it up though, anything else you would like to add about the shape she is in?
