Baldwin RF-16 ("Shark") sound decoder

Does anyone make a proper Baldwin Shark sound decoder? I have a pair of Bachmann HO ones and want to equip one with sound. Having never heard a rear Baldwin shark sound I can’t say if it is correct or not, but it would be nice to have the engine noise and horn match the prototype if possible.

Can anyone recommend one? I am willing to gut the Bachmann DCC motor-decoder if necessary.

Thanks.
