Hi Ernest,
Sadly, the locomotives were retired from service in 1934 and ultimately scrapped. According to the book "Milwaukee Road Narrow Gauge" by Tigges and Jacobson, which chronicles the history of the Bellevue & Cascade RR and its predecessors, both the bells and one of the whistles from these locomotives have been preserved.
The book is out of print, but remains available from a number of sources.
Hope this helps.
Best Regards,
Glenn
