I just heard back from Steward via Text Message - he is been very sick the last few months. I responded and hope to heard back that he is on the mend.
It will be interesting how it goes with the B30 and even if the heater is bad or falls apart I'll have the original bits I need (or more like want). After looking at Allan's (Retro Steam Tech) YouTube I think the top of the whistle on the B30 is correct, just the whistle was moved to the side for whatever reason. So I think I'll be in much better shape with the B30 parts, then without it.
I do have a DVM and before tearing it a part I'd be checking on it for sure. Thanks for the tip on ohms value, one less thing for me to search for ;-)
