A scan of the car is on Rail Car Photos –

The car is actually an older car than the Tangent model as it has a single row of rivets not a double row mandated in 1917.

I'm sure you meant not allowed in unrestricted interchange. :-)

But the January 1953 ORER shows no DRX reporting marks for anything.
I think that means the cars were no longer in Deep Rock service. There
is a Matt Herson photo of a vintage PTC Deep Rock tank car on the ChP
in Mexico in the 1970's - and it still has KC brakes!

===============================

  Problem with the Deep Rock is that it has KC brakes, and those were not allowed
  in interchange after (?) Jan. 1, 1953.
