Does anyone know of a parts list for IHC

I have an IHC 4-8-2 loco that some how I lost the reading tender and the front is of the boiler I missing but I have moved 8 times in 10 yrs so who knows were it is anymore but I tryed to look up the website but it is not there anymore and I would like to get the parts to fix it and get it running again I need the tender to make it work again. Any little help would be grateful. Thanks ......

can you add sound to a loco that has DCC in it already and can you add dcc and sound to older straight dc locos . sorry if it sounds like a dumb question but i want to go to dcc and sound but i dont want to replace every one of my old dc locos in my collection
