No one knows what happened to the MARC RDCs?

It's the first time I've really considered the RDC's... but it's a safe guess they were retired or sold off by 1995. I was riding the Camden Line to college then and never rode in them -- it was usually a MARC I or MARC II series, with the occasional MARC III.

9920 and 9922 are now Tennesee Valley Railroad Museum 20 and 22

What happened to...

MARC 9 - B&O 1902, 9912
MARC 11 - B&O 1905, 9915 - saw a photo of it coupled to another car at Brunswick in 2009, awaiting shipment to B&O Museum?
MARC 12 - B&O 1906, 9916
MARC 13 - B&O 1907, 9917

These are the only four cars I can't track down.

Thanks!
