Repowering Bowser Steam

[ptiller]

I'm throwing this question out to the members of the club, but also into cyberspace:

Is there anyone out there who knows anything about repowering/regearing a Bowser Old Lady Consolidation and other Bowser steam?  I built one, painted it up and it looks great.  It runs well, but it sounds like a coffee grinder gone wild.   I can't seem to find anything on the net about this particular engine, and not much about other Bowser steam engines. 

Thanks for your input. - Phil
