In the lower right hand corner of this 1909 boxcar is a stencil that reads "M. C. B.

Pocket Coupler". Is "M.C.B" Master Car Builders and what is a pocket coupler?

There were full size MCB couplers used on standard Gage equipment as well as 3/4 size that were popular with narrow Gage in intra-plant rr's. 

The full size MCB couplers were somewhat smaller than today's couplers. Tonnage wasn't as heavy back then. 

The coupler pocket is the same as a current day draft gear pocket. 

The coupler pocket appears to part of a full width car end casting. Whereas more modern car design attaches the coupler draft gear to the center sill.

So you are saying "pocket coupler", as stenciled on the car, is the same as "coupler pocket"?

bob:
it boils down to semantics, the MCB had
their own definition, you hsve to remember this was a transistory period
from single sheat to double sheat and
an increase of weight and stress
