Which decoder for the Baldwin Small Stock Tender?

[NevinW]

I haven't opened it up to look at the circuit board yet but which decoder would everyone recommend for the Baldwin Small Stock Tender (1910-1950) for the 4-6-0?  Is there a sound decoder that will fit? Assuming some minor surgery?  Thanks -  Nevin

Tsunami small steam.  I don't have a 4-6-0, but you should be able to put a speaker in the bunker under the coal load.
