[GreenKeys] Building Jack Fields

[Paul Wills (CKT&T)]

A Western Electric catalog from 1935 is available on the Telephone 
Collectors International Library site.

http://www.telephonecollectors.info/index.php/browse/document-repository/catalogs-manuals/western-electric/we-catalogs/doc_details/12257-1935-we-catalog-no-9-telephone-apparatus-and-cable-t1152-ocr

Drawings for a number of jacks can be found on page 122.

The 223A is not shown but listed later where it's referenced back to 
another number.
