Does anyone think it's possible that some sort of whistle information may be at UCONN? Maybe it's enough to get the manufacturer name...maybe we'd get lucky and get the musical chord. (shrug) While I've been to Storrs several times, I have to admit that's not something I've looked up.
I suppose the next question would be if the UCONN records even go back that far (pre-Trustees I)? IIRC, the last new steam loco order before the I-5's was in the late 1920's (before bankruptcy): the R-3a's?
