Tracing Pere Marquette passenger car numbers

Hi,

Anyone know if it is possible to trace passenger car numbers of the PM? Such as maker, when put in and taken out of service, etc? Any books, publications etc?

I am interested in cars 7783 and 7771 in particular.

The definitive book is Pere Marquette Passenger Car Pictorial by Arthur Million published by the Pere Marquette HS. I don’t see those numbers. Most had three digit numbers. Otherwise the highest I see is 1209, a heavyweight coach pre C&O.

Thanks.

Were all of the passenger cars PM used Pullman made cars?
