What happened to MARC RPO car?

Until recently a MARC liveried former railway post office car had been parked on Track 3 at Camden Station in Baltimore, Maryland. Where has it gone?

The MARC baggage car was recently donated to the B&O Railroad Museum and moved this week to the Museum property

I wonder if it was paired with MARC Cab Unit 5100. We could have a travelling exhibit with a MARC IIa/b pair as well, if there's any left. (I wonder about any MARC I's.)
