This is taken from Silver San Juan with me filling in the holes I know of.
0400 - sold at sheriffs auction 1962, sat in Ridgway, sold to GLRR (date ?) and rebuilt, on display at CRRM for now operating
0401 - To Boulder CO 1952, destroyed (date ?) RIP
0402 - To Knott's Berry Farm 1951, operating
0403 - ?
0404 original - scrapped 1895
0404 new - on display CRRM operating(?)
0405 - 0408 - refused on arrival due to poor condition never placed into service
0409 - to Narrow Gauge Motel , to Magic Mountain, to Woodmoor Corp. , to Heritage Square, to Japan
So all five cabooses that were in service at end of operations survived. 0401 was destroyed later and 0409 is in Japan never to return unless someone finds a lot of money. So that leaves up three in the States. Two in CO and one in CA, all three inn operating condition(I think).
