Anyone on the board know of or is well versed as an Nscale brass steam tuner? Although I can disassemle an Atlas or Kato, I am hesitant to tackle a Key Cab Forward as I would hate to start disassembling it and ruin the mechanism by not being able to reassemble it properly. If necessary send any info to me at FlyGuyB626@aol.com. Thanks, this board has been extremely helpful to me in my N scale adventures!
