One of the problems Ralph Messina had with his massive project to list the specifications for each Mark II in our data bases was that the Mark II Trim codes were established in 1955 and were not subsequently updated.

When subsequent trims combinations were produced official trim codings were not issued. In addition none of the unique DSO trim were supported by trim codes.

It was Ralph's objective to establish an augmented coding system for our data bases that included all trim combinations that were produced. Ralph teamed with Mark II "Guru" Lowell Domholdt to develop the following Augmented Interior Code Trims.

These codes are used in our databases and our Registry Histories.
