Re: C&IM 70-ton gondola car builder and date

Thanks for the clarifications. I found two images of C&IM 7199 in my 1937 CBC (overhead interior and near side view). The interior shot clearly shows the Murphy style ribs. The captions have the key data. If the Illinois Bituminous coal packing density weighed around 54 pounds/cu ft it would hit its load limit of 155,000 pounds without heap.
Actually, I believe I saw three types of end panel rib-ends: pointed (Murphy), flattened, and split or bi-forcated(sp).
So all came out of Pullman, but different plants?
1927 Lot 5423 Michigan City
1937 Lot 5562 Hammond
1948 Lot 5909 Butler
You have to wonder how much series-specific tooling they kept in their back lots.

Looked at my file on these cars last night - see my previous post on the STMFC list dated Feb. 17, 2005 (post #38786) for more post-STMFC info about these cars. There are a couple of errors in it. The following short roster is more or less correct:
C&IM #7000-7349 (350) cars BLT 7-27 & 8-27 by Pullman Standard Car Co. (Murphy inverse corrugated ends, 12" channel centersills)
C&IM #7350-7449 (100) cars BLT 8-37 (inverse Drednaught ends, double Z welded centersill and 70-ton National B-1 trucks)
C&IM #7450-7849 (400) cars BLT 7-48 (Murphy inverse corrugated ends)
By 1971, another (150) cars were added to the series, making it C&IM #7000-7999, but 1971 ORER data indicate that only 641 cars were live in that number series. Did not research these further because they are out of my time period.
The cars in the first three series were almost identical, differing only in placement of brake components and type of handbrake.
I have extensive measurements of one of the 7-48 built cars.
