Carsten's Special Passenger Cars

I have 3 HO cars painted for Carsten’s- Railroad Model Craftsman. They are:

Athearn baggage #6 “Fredon”
Athearn observation #4 “Ramsey”
E&BV coach #7 “Newton”

Did they ever do any other passenger cars? I know they also did a box car for Ridgely & Midland County and I think a 50’ plug door box for Carstens.

Thanks,
Roger
